Just gonna say this, I felt it at the time, I feel it now.
The problem with the play wasn't so much the decision, but the execution.
A pick play in short yardage like that can absolutely work. It's a pretty high percentage play, and there are practical reasons to resort to a pass when you've just tried a run play to Lynch and been kept out.
People forget, it was second down, the Patriots had their jumbo package out there, and they'd already stopped Beastmode once.
The real mistake was Carroll letting all that time run off the clock so he felt he had to risk a pass in order to maximize his chances to score. That's what people should be blasting Pete for. He wasn't disciplined when it mattered most.
If you're going to risk a pass, doing one on second down after Hightower kept Lynch out isn't particularly unreasonable.
However, the execution by the players themselves was abysmal.
Wilson could not have been more obvious about a potential throw to the right if he had a neon sign on his forehead. He doesn't look to the left even once in the presnap. There's no attempt whatsoever, either before or after, to sell a possible run play to the left. Those are the damning aspects of the play.
The fact of the matter is that Carroll's big failure is not the playcall, it's not managing his men and getting them to calm down and line up like professionals. They're all pumped about the Kearse catch, they're full of adrenaline, and Carroll failed to calm his troops down and ensure they played with discipline, and as a result the disguise failed and playcall could not possibly be more obvious. That's what allowed Browner to identify the offensive gameplan, pick Kearse and spring Butler. The Seahawks were acting like this play was a formality, and the Pats had more than enough information, and discipline, to punish them for it.
Oh, and Wilson's throw was itself slightly off target, he led Lockette by just a little bit too much which allowed Butler to muscle him out and get the ball himself. It wasn't an absolutely awful throw, but it was an imperfect one, and it helped the Patriots do what they needed to do.
This is why it's actually pretty darn rare for a "player's coach" to win Superbowls. There's times when you've gotta be the one to go in there and crack that whip, and you've got to have the credibility when you do to make dozens of pumped up, egotistical young men listen to you. Pete Carroll lost control just a little bit, couldn't keep his men's heads cool, and the result was an undisciplined play that led to disaster..
