If his weapons in the passing game remain healthy, I don't see why he can't have a season close to the one he had in 2012: 4,827 yards passing, 34 TD's, 8 INT's. Somewhere around there. From where I'm sitting, the following are the most important to him accomplishing that...
1. Health to Gronk, Amendola, Edelman, and Vereen.
2. At least one of the second year guys making the leap forward. Ideal if it's both Dobson and Thompkins.
3. Interior pass protection getting fixed. Whether that's Connolly at C, Cannon/Devey at RG or Stork coming back healthy and lining up at C with Cannon or Connolly at RG. Either way, that's been a major weakness two years running.
If all these happen, it's easy to see Brady enjoying a "renaissance" season and piling up some nice numbers. He looked fantastic last night. Razor sharp and decisive. You can tell the trust in his receivers has grown by leaps and bounds over where it was at this point last season.
