This team is a solid for a 12 team PPR league.
Arian Foster, Frank Gore, and Daniel Thomas makes for 3 solid RB plays. I don't expect Reggie Bush to have a huge impact in Miami, but if he does Thomas will atleast get some reps towards the goal line and on first and second down.
Miles Austin is a low end WR1 but I consider Brandon Marshall as a relatively high WR2. Those two compliment each other nice for decent value in your first two wide receiver slots. I don't love Braylon Edwards in San Francisco with Alex Smith, but new head coach Jim Harbaugh could improve that situation. Edwards has a chance to emerge with the 49ers, especially with Michael Crabtree missing significant time due to his foot injury.
Having three quarterbacks is a decent plan when Michael Vick is your starter and Matt Stafford is your backup. Tons of upside there but definitely significant injury risk.
Also, I would handcuff Arian Foster with Ben Tate. The Texans are decently high on Ben Tate, despite his injury troubles. If Foster were to go down, I'd have to imagine that the Texans would take the opportunity to phase in their young gun. Ward is 30 while Tate is just 22. I'm not sure how much Derrick Ward has left in the tank.
Good luck in 2011
