This is a very interesting era that we are entering into. The age of QB depth. Think about it. Troy started for 3 years. Then the Boekman buffer year before Pryor started for another 3. Followed by Braxton's 3 and possibly more. We are set up in the future to see QBs not get the keys to the offense until their Junior or Senior years. Which is somewhat scary given the body of work so far.
edit: The 3's are technically 2.5
