try to get him and see how it pans out.
I feel bad for Tua and the Dolphins fans, they might be better off tanking and drafting a new QB as I really don't see why Tua would come back, and the Dolphins would win tons of fans from all over if they tell him to retire. I get wanting to win and be competitive, but they really need to step up and show people they care more about the players health than winning games and making $$. The NFL would totally win some good will if they got involved in this too.
They have a lot of bad press from the whole concussion lawsuit. This could turn some of that around and really help them as a whole.
