Not crazy about the hair, but you're selling him way short if you think his dedication to the game or work ethic has changed ... just listen to his team-mates and coach and you'll find out that presumption would be very wrong indeed. You do not play the way he does by lifting Margritas in Rio while your competitors are in the gym.
If you saw his last game you'd see that is exactly the way he played.
I did see his last game ... that was not an indication that his work ethic has changed. It hasn't.
He was completely unprepared, his timing was incredibly off, made no effort whatsoever to scramble even once, and generally looked like a deer caught in headlights.
That was after a bye week to prepare.
If that and partying in Rio during the offseason is not an indication of reduced work ethic what is?
Ahhh ... that would be an indication of a bad game ... every athlete has them. If you listen to interviews of his team-mates and his coaches, you'll hear them call him a QB with one of the best work ethics in the game today. Pretty easy to take the whole Hollywood crap for the gospel truth, especially when someone's married to a supermodel, but personally I try not to judge a player by what the tabloids dish out and what the "general public" sentiment may be ... it's very often quite far from actual reality, and if Tom were the guy who lives the lush and un-dedicated life you're intimating here, there's no way he would hold his job any longer than it takes to clean his Oakleys. 
A bad game? We'd have had a better chance with Jeff Driskel.
He's lost his last 3 playoff games in a row now, two of them were at home, one was on a neutral field, he was favored in two, and he had a bye week in two of them.
I just don't think this is the 04 Brady anymore.
