here's my list of best fantasy players for this year:

QB: Manning, nobody does it as consistently
RB: Tomlinson, even with a lousy team around him puts up monster numbers. (Ahman Green is my second pick here and Holmes will also enjoy a solid season)
WR: Randy Moss, no question. no WR finds the endzone like this guy
TE: I'm gonna go with Shockey here, I think he can rebound from his injuries and put up great numbers. (Also, look out for Kellen Winslow!)
K: I guess i'll go with vineteri here. great kicker, as consistent as they come.
