1) WR Miles Austin - Cowboys
Without question, Austin has been the waiver wire pickup of the year thus far. If you've had him during his last two games, you've probably won.
Austin broke onto the scene in Week 5 with 10 catches for 250 yards and two touchdowns against Kansas City. During the bye week he replaced the ever-steady Patrick Crayton as a starter, and Austin proved his worth once again. Against a shoddy Falcons pass defense, Austin put up big stats: two more touchdowns, 171 yards, six catches.
At this point, Austin has become a must-start every week.
2) Vernon Davis - 49ers
Davis has never lived up to his substantial draft hype, but he's quietly putting together the best season of his career. He broke out yesterday, thanks to three touchdown catches from Alex Smith.
