While It is absolutely true that Brunell had an overall lower QB rating last year than PR (74.8 vs 63.0), the turnover stat is way off balance.
PR threw only
14.77% more passes than MB (272 vs 237), but had
83.33% more INT's.

A mediocre QB sure aint going to win you many games, but he can lose them very quickly.
