Brady is a bit of a long ball gunslinger and gets more deep ints than most but essentially those are the same as punts.
Cassel while he will try to stay conservative will find himself in a lot more come from behind situations than Brady will. Situations that often call on a QB to force a throw and thus add to his pick total.
No brainer: Cassel will have more picks just due to the fact he will have to take more chances in catch-up situations - (barring injuries to either that will shorten their seasons).
