Every week, well mine the waiver wire for lesser-owned assets to help your squad, whether you favor dynasty or the re-draft format -- and well also toss in some tips for DFS players out there. Categorized by position, the players are ranked in descending order by ownership percentage in ESPN leagues.Well also include some former go-to fantasy assets who may be overvalued -- in the short or long term -- for one reason or another.ForwardsConor Sheary, LW/RW, Pittsburgh Penguins Ownership percentage: 14.8Skating on a top line with Sidney Crosby and Patric Hornqvist has its obvious advantages -- just ask Sheary about the two goals, two assists and 16 shots hes accumulated from that spot in his past four games. While Crosby has the primary assist on both of Shearys tallies, the sophomores aforementioned helpers counted on goals scored by the Penguins captain. No coincidence here; hes worth an add while he remains on this unit.An additional Penguins note: Tumbling from Evgeni Malkins line once Chris Kunitz returned from injury, Jake Guentzel might be re-joining the AHLs Wilkes Barre/Scranton Penguins shortly. The 22-year-old would undoubtedly benefit from greater playing time in the AHL, though his immediate fantasy value obviously goes to zero when hes down in the AHL.Anthony Mantha, RW, Detroit Red Wings Ownership percentage: 8.6Hes big, he likes to shoot on net, and now hes playing on the Red Wings No. 1 line -- and power-play unit -- with Henrik Zetterberg and Tomas Tatar. With a hefty percentage of Detroits roster in the infirmary, Mantha should get an extended look in that prime role. And while junior hockey is a vastly different forum, Manthas scoring prowess with Val DOr (QMJHL) cant be overlooked altogether.Jason Zucker, LW, Minnesota Wild Ownership percentage: 6.7Last week, Mikael Granlund attracted our attention from his spot left of Mikko Koivu; this edition of Waiver Watch focuses on the Wild centermans right side. Thats where Zucker has comported himself admirably, with a goal and five assists in six games. Just dont ask for much power-play production from the 24-year-old, since hes not getting much work there.Michael Raffl, LW, Philadelphia Flyers Ownership percentage: 1.1Recently boosted back to the Flyers top line alongside Claude Giroux and Jakub Voracek, Raffl scored on five shots in nearly 18 minutes of ice time against the Predators on Sunday. When filling that slot, the 28-year-old is a serviceable fantasy asset in deeper leagues; hes much less so when he is elsewhere in the lineup.Alex Chiasson, RW, Calgary Flames Ownership percentage: 0.8After Sundays multi-goal output in a lopsided win against the Anaheim Ducks, the trio of Johnny Gaudreau, Sam Bennett and Chiasson is likely to be left intact. Take advantage of the lesser-owned right winger before the magic fades, especially in DFS competition.Trevor Lewis, C, Los Angeles Kings Ownership percentage: 0.4However long the assignment lasts, Lewis merits second thought in deeper fantasy leagues while competing on a forward unit with Anze Kopitar and Marian Gaborik (and not a moment longer). Scoring in two straight games, the typical depth forward played an uncharacteristic 17:30 in Sundays 5-4 shootout loss to the Canadiens. Alongside Kopitar and Gaborik, Lewis also has potential as an ultra-inexpensive asset in DFS play.DefensemenAndrej Sekera, Edmonton Oilers Ownership percentage: 10.2Often underrated as a fantasy asset, Sekera is starting to tangibly benefit this season -- four points in his last four games -- from the scoring talent around him. And we simply adore the 30-year-olds role on a top power-play unit with Connor McDavid & Co. While Sekera is no game-changer, he merits a blue-line depth role in most deep leagues.Justin Schultz, Pittsburgh Penguins Ownership percentage: 5.5Months after joining the Penguins last season, the 26-year-old is really coming into his own with his new squad. A disappointment in Edmonton after his rookie season, the former Oiler has recently exploded for three goals and three assists in four contests. Those numbers are wildly unsustainable, but just wait until the noted power-play performer starts contributing more with the man advantage.GoaltendersSteve Mason, Philadelphia Flyers Ownership percentage: 27.6Dont look now, but one of the games streakier netminders appears on the upswing. Following a ho-hum start to 2016-17, Mason has strung together four consecutive wins, along with a 1.71 goals-against average and .945 save percentage. If possible, exploit him while hes hot.Scott Darling, Chicago Blackhawks Ownership percentage: 24.5With Corey Crawford (appendectomy) on the injured shelf for two to three weeks, Chicagos crease briefly belongs to Darling. Enlist him as you would any decent goaltender for a top-flight NHL team.Karri Ramo, Toronto Maple Leafs Ownership percentage: 0.1One waiver transaction (Jhonas Enroth) plus one signed professional tryout contract later, and Ramo appears in position to earn the backups job with the Maple Leafs. After recovering from last Februarys knee surgery, the 30-year-old veteran should get a preliminary shot with the AHL Marlies once medically cleared. Between Avangard Omsk (KHL) and the Flames, Ramo has been a consistent professional presence in net since 2009-10 (previous seasons with the Tampa Bay Lightning were more volatile). Considering that Leafs coach Mike Babcock reportedly wants 20 games out of his No. 2 from now until the end of the season, Ramo might -- if the dominoes fall in proper order -- become fantasy-relevant once again.Lowered expectationsAlex Galchenyuk, C/LW, Montreal Canadiens Ownership percentage: 87.9In a depressing blow to the Canadiens, Galchenyuk has been ruled out indefinitely with a leg injury. Center David Desharnais -- who has a history of success with Max Pacioretty -- has been promoted to the top line alongside the Habs captain and a smoldering Alexander Radulov.J.T. Miller, C/LW/RW, New York Rangers Ownership percentage: 70.4Tucked within the Rangers bottom six -- and away from former linemate Kevin Hayes -- Miller isnt the same threat, as made additionally evident by his zero points in four straight games.Patrick Sharp, LW, Dallas Stars Ownership percentage: 63.5For the second time this season, Sharp is sidelined with concussion-like symptoms. Since this is a head injury, theres no point in trying to predict a return date for the 34-year-old. Just rotten news all around.Anthony Duclair, LW/RW, Arizona Coyotes Ownership percentage: 25.7Make no mistake, we believe Duclair has a bright future as a feisty, scoring forward in the NHL. But right now, the 21-year-old is stuck in the Coyotes bottom six (when he isnt a healthy scratch) and floundering. Fantasy-wise, thats uninspiring. If possible, owners in deep, dynasty leagues may want to bench Duclair for the next while until hes back in the top-six mix, while those in shallow leagues can drop him (if they havent already). Deebo Samuel Youth Jersey . Just as Montreal was settling into the first full working week of a new year, the Impact announced the appointment of their new head coach. Terrell Owens Jersey . The injury bothered Bledsoe in the Suns victory over the Clippers on Monday and he sat out the teams home loss to Memphis on Thursday night. http://www.49ersrookiestore.com/49ers-Steve-Young-Jersey/ . While hell be dialed in to that tournament on a course he loves, you can forgive him if his eyes glance down the calendar just a bit, towards April. Ronnie Lott 49ers Jersey . LOUIS -- Valtteri Filppula assisted on three of Tampa Bays four goals, and the Lightning beat the St. Frank Gore Jersey . After a first half in which he thought "the lid was on the basket," the Toronto Raptors coach watched his squad mount a second half surge to defeat the Cleveland Cavaliers 98-91.Danny Willett and Tommy Fleetwood both made encouraging starts to the Maybank Championship Malaysia as Nathan Holman set the first-round pace at Royal Selangor. Leaderboard Maybank Championship Malaysia Holman, who claimed his maiden European Tour title at the Australian PGA Championship in December, claimed the outright lead after carding a flawless seven-under 64, while the English duo of Willett and Fleetwood are just one stroke off the pace.World No 13 Willett, the highest-ranked player in the field, admitted he enjoyed an outrageous last 11 holes after being one over for the first seven, making five birdies and an eagle to charge up the leaderboard. The Dubai Desert Classic champion made back-to-back birdies at eight and nine, and he then pitched in for an eagle at the 13th before rolling in a monster putt of around 50 feet for birdie at the next. Danny Willett chipped in for eagle and holed two huge putts for birdie Willett picked up another shot at the long 15th, and his lengthy putt for birdie at the last looked to be racing past the hole, only to thud into the back of the cup and drop to cap an entertaining 65.Its a strange old game, he told Sky Sports 4 afterwards. We hit it close a lot on the front nine and made nothing until eight and nine. And then we took advantage of the par fives and holed two really long ones. It kind of goes in circles. You miss a few short ones and then you dont expect to hole a long one like that at 18, especially going at that pace, but Ill take it. Willett upstaged the likes of Rory McIlroy and Henrik Stenson to win his fourth European Tour title in Dubai a fortnight ago, and he added: Were doing all the right things. The work that were doing is the same, week in week out. The warm-ups and workouts are all the same so I am trying to keep the feelings as similar as possible but its a stupid game, isnt it?You can play well and shoot millions or you can scab it a bit and shoot a good score. Fortunately a few things went our way today so hopefully we can keep riding that wave and see what comes.Young Australian Holman did well to keep a bogey off his seven-birdie card, and he believes he can soon breach the worlds top 100 if he keeps up his current foorm.dddddddddddd Nathan Holman leads outright after a faultless 64 Every part of my game was quite good and I was saying a few weeks ago that my game has been trending in that right direction so it was nice to get a really good one in, said the 24-year-old.A lot of the guys probably havent played here. Its quite a tricky golf course and quite short so you need good lines off the tee and if you can get your wedges and putter going, you can post a score. It suits my eye. I quite like the look of it and obviously thats shown through with the score I had today so Im looking forward to the next three days.My immediate ambition is top 100 in the world and then move into the top 50 in a few years. Tommy Fleetwood also kept a bogey off his card in his opening 65 Fleetwoods 65 was also bogey-free, and he and Willett share second with Angelo Que, Peter Uihlein, Jorge Campillo and Alexander Levy, who shared the lead with Holman until making his only bogey of the day at the last hole.Louis Oosthuizen opened with a solid six-birdie 67, but Martin Kaymer has work to do just to make the halfway cut after the German offset four birdies with as many bogeys in an erratic level-par 71. Martin Kaymer slipped seven shots off the pace after an erratic 71 Meanwhile, four-time European Tour winner David Horsey was forced to withdraw after just nine holes, and he later revealed that he would soon be undergoing knee surgery which will sideline him until at least mid-April.Disappointed to have to withdraw from @maybankchampio1. Shooting pains up my lower back made it impossible to continue, Horsey said on his Twitter account. Now having a knee op on my R lateral meniscus on Tue, which puts me out until Spanish Open. Hope to be back fitter and stronger by then. Also See: Malaysia leaderboard Schwartzel wins Tshwane Golf live on Sky Sports 4 European Tour Schedule ' ' '
