Interesting story, thanks. I did hear about that and see no reason why players of either team would need to be measured for rings before the game. Sounds like an urban legend.
As for MM, hey a SB win is still a win, and he coached that team to success. There's another unproven theory that coaches should move on after 10 years with a team. I guess I agree with that, with the exception of Mike Tomlin.
For whatever reason, MM started coaching very good teams not to lose rather than how to win. I'm surprised Jerruh didn't fire him after the Packers whipped the Cowboys. MM will win a lot of games, just not the big ones with any regularity. The current NFL seems to have passed him by.
