Pick up Blair White if he's still available.
Joseph Addai and the running game is out; Dallas Clark is done for the year; Collie is gone for 4-6 weeks; and Gonzo re-injured himself. That leaves Wayne (double teamed), Garcon, and White (who the coaches are impressed with).
The rested and well-prepared Colts play the Texans, with their shitty secondary, next Monday Night in what is sure to be a shoot-out. Pick up Blair White and start him as your WR3, because he's going to be the next waiver wire gem to explode.
EDIT: I just grabbed Fitzpatrick, too. Any QB who can air it out against the Jets and Ravens is worth a pick-up in my book. The Bills have no running game and they're always playing from behind, so they're a pass-first team by default, plus their stud receivers are finally coming along.
