There is, however, a significant difference.
When Brett was peaking, he was the ONLY ONE.
Now, you have Culpepper, P. Manning, McNabb, Vick, Brady, and several others who could go either way.
Favre was ALONE. He was the NFL's "Golden Boy" because he was all there was to choose from.
So, in my opinion, part of the reason that Brett became as famous as he is is that there was no one else in that time frame on the rise...no one to gauge him against except previous QB's.
With the current QB stars in the NFL, there are other fantastic current
QB's to gauge them against. And, because there are so many of them, they tend not to stand out as much individually.
See where I'm going with this?
