Your top 15 look pretty good. Although Id drop Plummer behind Palmer.
I think Carr is overrated again. How he still goes ahead of Harrington, I dont know. Even as "poorly" as Harrington played last yr he was still more valuable than Carr - now that he has actual NFL calibur players around him he should put up substantially better fantasy numbers than Carr.
McNair below Carr? Again - when Im drafting that late Im picking upside and Carr simply isnt in McNair's league.
Big Ben is too high as well. He isnt a fantasy QB.
I would switch Harrington and Carr.
Id drop Big Ben below Boller.
Id put McNair ahead of Griese.
Finally I would rank Gus Frerotte ahead of Bledsoe.
Overall a nice job.
