I thought Glennon (chuckling at him with the Giants) and McCown were there before Jameis. *shrugs*
Anyway, I just checked and that 2012 Bucs had Vincent Jackson before the falloff, Mike Williams before the injury, and Doug Martin, who rushed for 1400+ yards and 11 TDs, so your view on "a better supporting cast" kinda fails, especially factoring in the run attack . And they finished 9th in yard and 13th in points with Freeman finishing 9th in yards and 7th in TDs, which still doesn't line up with what I said. You don't finish (as a QB) #1 in yards, #2 in TDs and lead the #3 team in both points and yards and not be a starting QB. I'm just saying.
