So which would you rather have? The sacks or the picks? Because Rodgers would throw it if someone would get open, Favre would often throw it no matter what.
The picks. Brett threw about 10 more per season than Rodgers, but Brett also took far fewer sacks which resulted in fewer yards lost and more first downs gained. And, when you move the chains, you increase your chances for points, which then directly correlates to wins.
It isn't rocket science why Brett Favre wins wherever he goes.
