re: Better in their prime : Favre or Rodgers?

Rodgers, but it's close. Favre was a monster in the mid-90s. The only QB on Favre's level at that time was Steve Young, but Favre balled on Young almost every time they played (Catch II notwithstanding).

Rodgers is simply the most efficient QB in the game in addition to being the total package talent-wise. For all of his elite throws, he doesn't force ANYTHING. Favre forced a ton and could sometimes get away with it. Rodgers calculates, then decides, then throws as needed, all in like half a second.
