Shit, this would be the best QB that the Phins would have in the past 20 years. Besides, this is right down the Miami's alley.
I agree however, here is my opinion why it would be monumentally stupid. No knock against Peyton he is a great QB and leader. He has had a spectacular run but...
First off huge risk, we still don't know if he can play, and if he can play how good is he going to be? Second, this is a win now philosophy. Everything the Dolphins have been doing has been building for the future, IMO we would need to bring in some free agents on the defensive side of the ball as well as another veteran receiver. Ask the jets how putting a piece meal team from free agency has worked out for them?
I would rather see the Dolphins take a chance on RG III and continue to build the team with talent then have 1 or 2 successful seasons and go back into the crapper.
