Week Two showed us just how unpredictable the NFL is, and just how inconsistent performances can be. For this reason, bench depth is vital, and making moves is even more vital. Don't sit on your hands and miss out on that key player, who can help you down the stretch. Some may have an impact, and some may not, but engage, and get to that waiver wire. With that said, here are some key players that may reside on your waiver wire:

QB
Matt Cassel, KC - He went undrafted in many leagues, including a fair amount of 12-team leagues. But his matchup this week is too good to pass up going against the New Orleans defense which coughs up points to everyone.

Kevin Kolb, ARI - Much like Cassel, Kolb went mostly undrafted but now finds himself under center for one of 6 undefeated teams in the NFL. His stats are less than stellar with only 2 passing TDs (and one rushing TD), but for depth, he's still better than a Brandon Weeden-type of QB3.

RB
Andre Brown, NYG - Ahmad Bradshaw got hurt and Brown stepped in and put up good fantasy numbers. Bradshaw is questionable for Week 3, and if he doesn't play I like Brown as a fringe starter/flex.

Mikel Leshoure, DET - The team welcomed him back from his two-week suspension on Monday. While Leshoure doesn’t help much in the passing game, many expect him to have a big role right out of the gate for the Lions. It’s worth grabbing to see how things unfold, but it may be risky putting him your lineup right out of the gate.

WR
Mohammed Massaquoi, CLE - Massaquoi, not Greg Little is proving to be the go to receiver in Cleveland. That's still not a juggernaut position from a fantasy perspective but he does 15 targets over the first two weeks. I like Massaquoi the most amongst the Cleveland receivers at this point although he's still not a starter, until I see more from Brandon Weeden against actual defenses, instead of the Bengals.

Donnie Avery, IND - With Austin Collie out, Andrew Luck has targeted Avery 18 times thus far. He's a sneaky type of player in fantasy, and always has been. In deep leagues, you could do worse at WR3 or flex than Avery, but don't expect him to carry you to victory.

TE
Dante Rosario, SD - I'm putting Rosario on this list out of obligation only. He had 3 touchdowns last week and that can't be overlooked. But, if you expect anything close to that type of performance again from Rosario, you're setting yourself up for disappointment.

Kellen Winslow, NE - Aaron Hernandez is out for several weeks with an ankle injury and the Patriots have signed Winslow to fill their need in their 2-TE set. That will move all the focus to Gronk, and leave Winslow forgotten. I'd take a wait and see approach on Winslow at this point, but with his receiving abilities, he could be a great grab for fantasy owners in this offense. Do it now, before he goes off, especially if you have endless waiver moves.

Honorable mention (put on your watch list, but don't grab yet): Curtis Brinkley, RB SD
