hogskin, just cause they started winning with him doesn't mean he's awesome, it could have been that the last guy was just REALLY bad... though i'd agree that he's a very important (and good) part of the offense... him and T.O. are the #1 and #2, and they seem to be able to make things go just fine...
anyone who wouldn't take daunte or mcnabb over ramsey is silly... though i wish daunte didn't fumble so damn much
for leftwich, i don't know, i've never been on BL's bandwagon, and i've watched him a couple times, but not enough to really know if he's worth much...
i would take ramsey over flutie, testes, boller, feely, warner, grossman, dorsey, mccown, rattay, and maybe leftwich or bledsoe, and i wouldn't trade him for oldies like gannon or maddox (not that old i know)... i know that gives him benefit of the doubt...
as far as 2nd stringers, gus, roth., or collins would be decent... manning is in a different class (money/talent wise), and for a future elite QB is still raw (his bro came in much more polished)...
that about as extensive as i can be without really refering to stat charts, tape and the like...
