It's late in the fantasy football season, but that's no excuse to ignore the ever-important waiver wire as a legit option to keep roster depth stout.
Forget roster depth—each week, a few gems emerge who can instantly upgrade lineups now that they have made themselves known to the world.
Whether it's an injury clearing the way to more playing time, an ineffective player needed replaced or a variety of other factors, the following gems not only had big performances a week ago but also have a chance to continue the strong production for the remainder of the season.
Don't miss out.
Note: Ownership percentages via ESPN. The Cleveland Browns, Kansas City Chiefs, New England Patriots and New York Jets are on a bye.
Jason Campbell, QB, Cleveland Browns (5.0 percent)
Quarterback is a deep position, so the waiver wire is often not necessary.
Jason Campbell is the exception.
While Cleveland is on a bye in Week 10, Campbell needs to be added as soon as possible. Since taking over the starting job, Campbell has thrown for 555 yards and five touchdowns to no interceptions in two games.
Any quarterback throwing to Josh Gordon and Jordan Cameron is a must-add, but the veteran Campbell is especially the case with the way he takes care of the football.
Aaron Dobson, WR, New England Patriots (4.8 percent)
Tom Brady is back, as referenced by his over 400 yards and four scores in Week 9 against Pittsburgh. That's great news for Aaron Dobson, but it gets better—Kenbrell Thompkins was a healthy scratch from the same game.
In other words, Dobson is officially a starter and the third option behind Rob Gronkowski and Danny Amendola, which is not a bad thing in any way. Dobson played on 68 of 75 snaps in Week 9 and caught five passes for 130 yards and two scores.
Not only is Dobson a must-add, but he's also a starter with high No. 2-receiver upside.
Donald Brown, RB, Indianapolis Colts (5.1 percent)
Trent Richardson's loss in Indianapolis is a gain for Donald Brown.
In Week 9, Richardson continued his disappointing campaign with the Colts since coming over via trade and only gained 20 yards on eight carries.
Brown ended up eating into Richardson's snap count with six carries of his own, which he turned into 49 yards.
The rushing numbers for Brown would have been higher had the Colts not been playing from behind, but he is clearly the change-of-pace back and preferred option on passing downs. His potential to contribute on the ground and through the air consistently makes him a solid add in all leagues.
John Carlson, TE, Minnesota Vikings (0.1 percent)
It's always tough to recommend a fantasy player in Minnesota who does not have the initials "AP," but tight end is typically a solid position to go with, especially if Christian Ponder is under center.
With that in mind, John Carlson is the way to go now that star tight end Kyle Rudolph will miss at least a month with a foot injury, per the team's official Twitter account:
Last week, Carlson had his best day in Minnesota with four catches for 23 yards. There is potential here for an increased workload as the No. 1 tight end on the depth chart, so Carlson's worth a precautionary add on the chance he explodes—he'll certainly have a big opportunity over the next month.
