I keep reading that Bledsoe is not a good fantasy QB, but that was with NE. Might be better with Buffalo, don't know yet.
Vick needs another year to mature, but might be a good plugin for a bye week, or a matchup decision. His ability to run will definitely help, his passing skills should improve throughout the year.
Pretty risky at WR, Driver will not be #1 in GB, Ferguson will (at this point). Bates is a good sleeper pick for a #2, because Alexander is slacking and Bates is snaring everything in sight. But that could change before the season starts.
Picking Indy for a D is asking for trouble, even though Dungy has done some good things, they're unproven. I think they'll still be below average, but ya never know...
I'm assuming you're referring to Ahman Green and not William Green, he's a solid RB, and if Favre can't get in sync with his new receivers, expect his workload to increase (which also increases the chance of fatigue/injury). George is definitely not a stud anymore, but way above average and could surprise. I'd get both of their backups for insurance (Ki-Jana Carter and Skip Hicks), or pick one and get another RB for your bye weeks.
Then again, I haven't played on a TSN league, so my strategy may not apply to your situation. 'Grain of salt' is the key phrase here.
