I mean this tells you 2 things.
1. There just aren't a lot of great quarterbacks out there, so if you have one in your stable that you feel "can be good", it's hard to lose the grip on that QB because then you have nothing. Whether I agree or disagree on what RG3 can be . . . I understand this move.
2. What is Miami waiting for? Are they trying to work out a long term deal with Tannehill first? Why so nonchalant in regards to exercising Tannehill's 5th year option? I've never been his biggest fan but even I realize how important it is to exercise that option and eventually work out something longterm, as I'm guessing that is the intention.
Would seem to be the most loigical explanation no?
