I don't dispute anything Belichick does.
If you're going to send the message to your defense that they're either too gassed or can't hold by going for the two yards in the first place, you really can't compound that message by ordering them to lay down.
It's a long season. Belichick gambled and lost. The two teams will meet again in the playoffs and the result will be different. The Pats pretty much dominated most of this game.
