These Week 15 fantasy duds could be fantasy studs in championship week

Look, dud performances are gonna happen, even with the game's best players. You can't write off a proven fantasy asset just because he's coming off a quiet week. Here are three guys who struggled in the fantasy semis, poised to turn it around in title week...

Matthew Stafford – The last time Stafford faced the Bears defense, he passed for eleven zillion 390 yards and a pair of scores. The December version of Chicago's D is far less engaged than the group he already torched. Start Stafford with confidence.

Tre Mason – If you somehow squeaked into the championship matchup with Mason in your fantasy backfield, you cannot sit him now — not against a Giants defense that ranks 30th against the run. Let's remember that Mason had respectable weeks against a few of the league's best run Ds, including the Seahawks, Broncos and Niners.

DeSean Jackson – Not only is D-Jax facing the team that kicked him to the curb in the offseason, but that team also happens to allow the most fantasy points to opposing wideouts. This might very well be a bloodbath, if RG3 manages to not mess it up.

And if you need a flex play for trophy week...

Then Fred Jackson

is most definitely your guy. Fred has quietly been seeing 20-plus touches per game recently, and he'll be facing an Oakland defense that allows the second-most points to opposing RBs. F-Jax is a layup start, really, likely to deliver RB1 numbers in the fantasy season's most important week.
