Marrone coached scared and made multiple game management mistakes. I consider that choking but it could just be Marrone being Marrone.
From taking a knee with two timeouts and a minute left in the 2nd quarter, to castrating Hackett and his working game plan at halftime, to becoming criminally predictable on offense in the 4th quarter, to neutering the most talented defense in the NFL by forcing them to play a soft prevent/zone D, to not letting the clock wind down to the 2-minute warning - handing Brady an extra timeout. It was really, really bad.
People like to throw their hands up and say "Well, what can ya do? It's Brady and Belichick!" Marrone had a talent-laden roster at his disposal more than capable of beating Brady. You don't beat Bradichick by playing the ole Play Not To Lose game.
