I still think the Bills team that went to 4 straight SB's was a better team. How much better would their legacy be if Norwood hits that 43 yarder. The Bills also had the misfortune of playing against a true dynasty team (Cowboys) twice.
When I think of dynasty teams I think of teams like the Steelers in the 70's and 49'ers in the 80-90's. Teams that acutally had a few blowout/dominant wins in the SB.
Personally, I think the description 'dynasty' is an overused term.
