Waiver-wire news changes throughout the week as injuries and depth-chart shenanigans overtake us. So be sure to follow me on Twitter by clicking on the link next to my headshot at the bottom of the column, and I'll keep you updated as news warrants.
Let's get to the best fantasy roster additions heading into Week 15:
Standard ESPN league finds
Jonathan Stewart, RB, Carolina Panthers (owned in 47.4 percent of ESPN leagues): Until Sunday, Stew Beef had averaged around 11 carries per game when he was healthy. In Week 14, he got 20 totes and responded with 155 rushing yards, a number which is, of course, skewed by his breakaway 69-yard TD. But the film doesn't lie: Stewart was terrific, albeit in a good spot against a bad New Orleans Saints run defense. With a solid remaining schedule (TB, CLE, @ATL), Stewart would figure to be a nice flex at minimum, but DeAngelo Williams could return to action and wreck it. D-Willy has a broken bone in his hand, and is considered questionable for Week 15. If Williams plays, Stew Beef loses some of his luster.
Andre Williams, RB, New York Giants (32.5 percent): Williams also got to face a soft run defense in Week 14, and responded with 147 yards from scrimmage. The Giants' remaining schedule isn't quite as easy as the Panthers' (WAS, @STL, PHI), plus Williams is actually Rashad Jennings' backup. Jennings was active Sunday but played only 16 snaps on his injured ankle; if Jennings gets healthy this week, Williams' workload will probably decrease. And the problem is, we won't know about Jennings until we actually see him play. So there's tons of risk relying on Williams, but some fantasy squads won't have a choice. He's not an instinctive runner yet, but the rookie is a thumper and showed good straight-line acceleration on his 50-yard TD.
Donte Moncrief, WR, Indianapolis Colts (14.0 percent): Reggie Wayne has a torn triceps and it's possible he won't play again this season. If that's the case, Moncrief will likely get the promotion he should've gotten weeks ago, as Wayne really doesn't look like he can play anymore. Moncrief made a big catch to set up the Colts' winning score Sunday, and played a career-high 45 snaps. I can make a case that as Andrew Luck's No. 2 wideout, Moncrief would deserve to be in the WR3 conversation every single week.
Baltimore Ravens defense (42.3 percent): The Ravens are just beneath my 50 percent threshold for this column, so they get the top spot as the defense that gets to face the Jacksonville Jaguars. That said, if you've been riding my St. Louis Rams recommendation from a couple of weeks ago, keep it going against Drew Stanton and the Cardinals Thursday night. And if you need a slightly deeper find, try the New York Giants (37.7 percent), who've scored 9 and 25 points the past two weeks in plus matchups, and get to host Washington in Week 15. (Washington has added 7.5 fantasy points onto the averages of the fantasy defenses they've faced in the past five weeks.)
Handcuffs: It's playoff time. As the weeks go by, your remaining opponents are going to be strong, and hopefully you've got the studs to keep up. Middling roster options with potential no longer need apply; rather, you're better off using roster spots backing up your RBs. Here's a list of current handcuffs you should own: Knile Davis, RB, Chiefs (23.8 percent); Carlos Hyde, RB, 49ers (14.3 percent); Alfred Blue, RB, Texans (40.6 percent); James Starks, RB, Packers (5.3 percent); Joseph Randle, RB, Cowboys (4.2 percent); Robert Turbin, RB, Seahawks (3.0 percent); Branden Oliver, Chargers (22.4 percent); Ka'Deem Carey, RB, Bears (1.4 percent).
Other solid waiver adds, about whom I've written in previous weeks: Mark Sanchez, QB, Eagles (40.7 percent); Latavius Murray, RB, Raiders (31.1 percent); Jarvis Landry, WR, Dolphins (33.6 percent); Jordan Cameron, TE, Browns (36.2 percent); Dwayne Allen, TE, Colts (49.1 percent).
Speculative standard-league finds
Harry Douglas, WR, Atlanta Falcons (2.2 percent): Julio Jones submitted an incredible Monday night with 11 catches for 259 yards, but he left the game early with a hip injury and as of this writing, it was unclear whether he'd be able to play in Week 15. If he misses time, Douglas would inherit a juicy role versus a leaky Pittsburgh Steelers secondary. The Falcons are suddenly getting more protection from their offensive line, and Matt Ryan has back-to-back 350-plus-yard games.
Kerwynn Williams, RB, Arizona Cardinals (0.2 percent): Stepfan Taylor (8.7 percent) started Sunday's game and looked pretty good. But Williams did a bit of work in the second quarter, then came out after halftime and ripped off a series of impressive runs through a Cardinals O-line that hadn't done anything for more than a month. That will probably get Williams more action going forward, though Taylor and Marion Grice (3.7 percent) will still be involved. Unfortunately, Arizona's schedule (@STL, SEA, @SF) will not lend itself to much fantasy glory.
Marquess Wilson, WR, Chicago Bears (0.1 percent): Brandon Marshall is out for the season, so there are targets to be had in the Windy City. Josh Morgan (0.0 percent) could also be in the mix, but Wilson looks like the upside guy to me. The Bears held onto him after he broke his collarbone this summer, and he looks the part: He's 6-foot-4 with 4.51 40 wheels. He's a bit wispy, but is still an interesting prospect who figures to get an audition with Jay Cutler at the end of this lost season.
Ben Tate, RB, Minnesota Vikings (30.1 percent): How much longer must we proceed with this Matt Asiata charade? The dude just isn't a feature back. He had 19 carries Sunday and literally none of them made me take notice. He's a fullback. Tate played only 10 snaps (an increase from zero and seven the two previous weeks!), but injected a bit of life in the fourth quarter. The Vikings should be looking at him a lot, to see if they want him around to pair with Jerick McKinnon in '15. Will they? We'll see.
Other speculative standard-league waiver adds, about whom I've written in previous weeks: Johnny Manziel, QB, Browns (10.3 percent); Doug Martin, RB, Buccaneers (38.4 percent); Khiry Robinson, RB, Saints (9.9 percent); Matt Asiata, RB, Vikings (31.1 percent); Charles Johnson, WR, Vikings (1.6 percent); Davante Adams, WR, Packers (14.4 percent); Andrew Hawkins, WR, Browns (32.8 percent); Stedman Bailey, WR, Rams (30.4 percent); Kyle Rudolph, TE, Vikings (23.2 percent); Mychal Rivera, TE, Raiders (20.2 percent).
Nate Washington, WR, Tennessee Titans (2.9 percent): Justin Hunter is out for the season, and Kendall Wright missed Week 14 with a broken bone in his hand. Wright is considered questionable to return this week, which could mean Washington gets another spin as the Titans' top wideout. Of course, Sunday that led to only three catches on three targets, but Washington did run more routes than he had in any game this year. Alas, Jake Locker will be his quarterback in Week 15, but he does get to run against a bad New York Jets secondary.
Kamar Aiken, WR, Baltimore Ravens (0.0 percent): Torrey Smith was active for Week 14, but his knee swelled up during pregame activities and he didn't play a snap. In his place, Marlon Brown (0.0 percent) and Jacoby Jones (0.1 percent) saw increased playing time, but Aiken was the biggest beneficiary, with seven targets and six catches and a go-ahead red zone score. He'd have some deep-league appeal if Smith is out this week against the Jacksonville Jaguars.
Other solid waiver adds for deep-leaguers, about whom I've written in previous weeks: Juwan Thompson, RB, Broncos (2.3 percent); Lance Dunbar, RB, Cowboys (0.9 percent); Stepfan Taylor, RB, Cardinals (8.7 percent); Marcel Reece, RB, Raiders (0.4 percent); Malcom Floyd, WR, Chargers (27.6 percent); Robert Woods, WR, Bills (6.0 percent); Marqise Lee, WR, Jaguars (2.0 percent); Andre Roberts, WR, Washington (0.9 percent).
