I actually thought it was the right play as well...however, my reasoning for it, didnt play out.....
I figured his thought process was, either we make it, and win the game, or if we dont, then the Colts score faster by the short field, and we have time to move back for a FG to win..
However, the linebacker made the mistake of tackling the RB at the 1 yard line with over a minute to go.....once they are that close, let him score, then u have brady, moss, welker and 1 minute to get a measly fg...
thats why i figured he did it, but then the defense didnt let them score, so my reasoning for it went out the window
