I would have liked to have seen how a Bears/Dolphins SB would've turned out. They coudn't have done worse than the Pats, and may have actually made it close. The way to beat the '85 Bears was to be able to throw it deep, which was the Dolphins strong suit. The Bears killed their playoff opponents because they all had to go to Soldier Field in the snow & cold (they obviously were a great team already, but the weather gave them more of an edge), but the SB was in the dome, so weather wouldn't be a factor. Turf definitely would have helped w/ the Marino/Duper/Clayton attack. On the Bears side, they'd have McMahon at QB, whereas their loss to Miami came w/ Jimmy Mac on the sidelines.
A very interesting "what if?".
