Really? Brady has played over 20 freaking years! And outside of 2008 he has been the Cal Ripken of the NFL. Tua in 4 years gets put on IR getting out of bed in the morning. Now FTR I don't fear Brady at this point but in a timing based offense where he gets rid the ball faster than anyone he would be a significant upgrade over Tua in Miami.
Of course it's JMHO...
