Is tom brady pretty much done?

Honestly I think Tom Brady is pretty much done. He just doesn't look good anymore. I've watched many games this season and even though the patriots are 6-2 brady looks really bad in my opinion. He doesn't even have 1 300 yard game, and he barely has 14 td pes in 8 games. He just doesn't look like th comfortable red hot Tom Brady that he was before. Guys like phillip rivers, Mark Sanchez, drew brees, all seem like they complete pes every down. With Brady I don't sense that anymore like I did a couple years ago. They don't even throw the long ball at all with him cause I don't think he can do it anymore. They're the only team I see that doesn't throw the deap ball. Do you think the patriots should try to draft a good strong young QB in the draft with one of their early picks, and maybe look to switch it up next season? Cause honestly I don't know what exactly happened, but Brady doesn't look like the guy he once was.
