Brady all the way. Although Carolina has been good against the pass, they haven't really faced anyone like Brady this season, so in my eyes, they haven't proven that their pass defense is actually as good as their stats show. And with Gronk back in full form and NE coming off a bye, allowing their receivers to get healthy, I think there is no way they stop Brady.
Also, Miami is actually surprisingly good against the pass. Rivers is just too up and down for me to be confident in him.
