how wonderfully simplistic. What's better beating the Patriots 15 out of 16 times or beating the Westchester High School fighting Quakers 16 times straight? Strength of schedule means alot, the '72 fins had one of the easiest schedules in NFL history. I'm not saying that the '72 fins weren't a great team. But the 17-0 record isn't nearly as impressive to me considering who they were playing. Heck they only beat the Bills (who sucked most of the 70's) by one point. If I remember right Buffalo missed a FG late in the game, we decided to make that a trend in the early 90's as well. Chicago won 18 games that year, in the playoffs they were virtually untouchable.
I should point out that I'm playing a bit of the devil's advocate here. I've been known to defend the '72 fins when they are questioned. But since everyone's a fin fan here I'll go for the '85 Bears to make life interesting. BTW I think the '85 Bears would have beaten the fins, better size and speed in the 80's .
