Matt Flynn had a much better year and barely got drafted as a seventh round pick. Fortunately for him he beat the odds and finally got paid this offseason. If Mett isn't a first round pick he will come back. And there is no way in hell he's a first round pick
Matt Flynn doesn't have half the arm of Mett and is much shorter.
Mett is a prototypical NFL QB in terms of size and arm strength.
He would be drafted after a combine this year. Not very highly, but he would be drafted.
Obviously he should come back however as he could be a VERY high pick next year will a full stellar season under his belt.
