My guesses:
Pats 27, Colts 24. With :36 left, Adam Vinatieri shanks a FG from the 12 yard line that would put the Colts up, then on the ensuing Patriots possession, a screen pass to Lawrence Maroney puts the Pats at the Colts 37, and Gostkowski sends a 55 yard laser between the uprights with :02 seconds counting down.
Saints 30, Bears 23. Drew Brees throws two interceptions, one of which is returned for a TD, Reggie Bush drops a fumble on his own 12 yard line which is returned for a TD, Devin Hester returns a 109 yard kickoff for a TD, and Drew Brees is sacked for a safety. Rex Grossman never crosses midfield. Karney runs 7 times for 12 yards and 3 TD, Marques Colston catches an 89yd TD reception, and the ensuing PAT snap is bobbled and fails to convert, Carney stuns the stadium by executing a fundamentally flawless field goal from 45 yards, putting the Saints a full 7 ahead.
