I'm surprised to see Steve Young so high on the rankings.
I liked watching him play and he was a great QB but I don't think he ranks with the greatest of all time. If he would've stayed in Tampa, He would've been the next JIM ZORN!!!
Some guys that should be mentioned with the greats that I haven't seen mentioned:
Fran Tarkenten
YA Tittle
Dan Fouts
Favre is TOP 5 all time in my book, Probably TOP 2 only behind Montana.
