I'm a Pats fan since that Superbowl against the Bears. Still hurts!!
Mike Greenberg was talking about how Seattle's defense can't be considered for greatest ever because they gave up all those yards to Brady, especially in the fourth quarter, and lost. He said that the 85 Bears wouldn't have allowed a comeback like that. That's conjecture.
First off, the 13 Seahawks and 85 Bears both won the SB in dominating fashion.
Secondly, the 85 Bears played an average Patriots side while the 13 Seahawks played a record-setting Broncos side (still for my money the biggest beat down in SB history considering all factors; everyone knew Chicago would win in a rout, and they were likely fortunate NE knocked off Miami).
Thirdly, the 14 Seahawks repeated as conference champions while the 86 Bears choked (the 86 Bears defense was
better than the previous side, statistically and continuity wise).
Finally, I have no doubts Brady
could have done the same against the 85 Bears, all factors considered. He did so against the 14 Seahawks, and Marino did so against the 85 Bears in Week 13, putting up 31 first half points, and 270 yds and 3 tds (high passing totals in those days) in a 38-24 win, Chicago's only loss that season.
Btw, San Francisco was closer to going unbeaten in 1984, losing in week 7 at home to Pittsburgh, 20-17. I'd still rate the 84 and 89 49ers and 07 Pats as better than the 72 Dolphins and 85 Bears. But as previously noted, the 85 Bears became media darlings and fan favorites and have been over-hyped for years, great one season side they were (00 Ravens had the best single season defense ever IMO).
