Here's my other major scenario: (1) Brady plans to play another 5-6 years. (2) At a minimum, he gets one more extension from the Patriots past 2014. Let's say, for the sake of argument, that he is extended through 2017 or 2018 (your choice). (3) That said, you are not required to assume that Brady actually finishes out the contract (if you prefer to consider that possibility). (4) Mallett will not wait that long for a chance to start. Either he's traded or signs elsewhere. So how would you find the new starter in that case? Would you risk pulling a 2011 Colts, if such a scenario were plausible?
