Let's not forget about Mike Smith in Atlanta. Granted, they were able to draft Matt Ryan but think about all of the turmoil with Michael Vick, Booby Petrino, etc. before he got there.
Smith's three years in ATL:
2008 11-5 (Ryan's rookie year)
2009 9-7
2010 13-3 and a 1 seed in the NFC.
My vote goes for the unheralded Mike Smith.
