Just reported on NFLN by Rachel Nichols: "I ask Belichick how he slept this week at this hotel, and he said "Like a baby" I am 100% convinced now that BB's demeanor this week is because he knows he has the keys to winning this game figured out. The saying of sometimes the game is won before its played comes to mind. Now many coaches have been overconfident leading up to a game. Simms said Harbaugh told him they were sure they would win the night before the AFCCG. But this is out of character for overpreparer BB. I think there are mismatches he knows he can exploit, and he has great confidence in his game plan based upon his demeanor.
