Even in his prime Brett was famous for multiple interceptions in multiple games. Not two or three ints. Try 5 or 6 per game. There's no defense on earth (MN's included) than can surmount that kind of action.
Dilfer, Manning and JOhnson were QBs who do not lose games. Brett Favre is the exact opposite of that group.
I don't recall very many games where Favre three 5 or 6 INTs. Can't be more than a handful. But he has thrown more INTs than anyone in NFL history.
It's true he has faded down the stretch more than once, but it's also true he has done the following:
- Thrown for more TDs than anyone in NFL history.
- Thrown for more yards than anyone in NFL history.
- Completed more passes than anyone in NFL history.
- Made the Pro Bowl 10 times.
- Won a Super Bowl.
Favre can lose games, but he also wins a lot too. I wouldn't even mention him in the same breath with Dilfer, Eli, and Johnson, especially Eli, who might be the luckiest QB in the NFL.
What those three very mediocre QBs showed is you don't need a great QB to win a Super Bowl. Favre doesn't have to be great in Minnesota. He just has to be good, or at least better than Tavaris Jackson and Rosenfels.
