The original post is what is wrong with so many teams. How many Heisman winners or candidates don't even play in the NFL now? Leinart? Brohm? (I think he might be on a the 4th guys in GB but you get it...) Shuler? Weinke?
People have forgotten that you don't just plug a guy in and watch the bulb turn on. It worked with Peyton and Eli but...well...they're Peyton and Eli and they didn't exactly burst out of the gate. They just stuck it out somehow. Aaron Rogers wasn't a Heisman but he is here to stay because he sat the bench for all those years, as is Matt Cassell, as did some guys who are getting old now (Favre, Brady, Hasselback).
