No. Only an idiot would think that. There's nothing wrong with his mechanics. Lots wrong with his teamates execution and as a result his ability to, though. The anecdote for that isn't film study as much as practice. Unfortunately they've managed to get him hurt to the point he missed his first two practices of the season due to multiple difficult injuries for any QB to play through. Although it isn't the first time he's had to deal with that situation.
You contradict yourself because you claim the problems are not Brady's fault - they are his teammates - but then you conclude that Brady needs to practice more. How is Brady's practice schedule effecting the sieve known as the OLine?
Brady needs to get into the tape. He has missed some reads this year - more than he has during his peak. Furthermore, he has missed some throws but that is indicative of a gradual recess of his mechanics caused by the fact that he is getting absolutely slammed out there. Again, it will return for him when he starts getting protection -which of course has nothing to do with him practicing.
