Let's be honest... Brady and Belichick can't win without one another. They had the refs in their back pockets for twenty years ever since the tuck rule was invented on the spot for them. Countless cheating incidents (spygate, deflategate, etc) also helped them. Both of their times are finally up. I say good riddance to both!
So what? Everybody knows its a thousand times easier to play QB in the NFL nowadays than it was 20 years ago. Every single rule change has benefited the offense. Comparing any starter to a career backup is not valid in the least. Also, how about the teams he has put those numbers up against?
