What bothered me was not particularly the decision to go for it, but that it seemed spontaneous and unprepared. I don't think we were prepared for a close game coming down to the last 2 minutes.
If BB knew on 3rd and 2 that he was going to take 2 downs to go for it then he should have run on 3rd down, forcing Indy to burn their last timeout. Then it might have been closer on 4th down, and we would have burned up more of the clock and left Indy with less time and no timeouts if we didn't make it on 4th down. Also, the 4th down play would have come inside the 2 minute warning and would have been reviewable.
Also, if BB made a decision that his defense couldn't stop Manning from 70+ yards out, then he should have had a strategy that if we turned the ball over on downs we would allow them to score as quickly as possible in order to get the ball back in TB's hands with time remaining to drive for a game winning FG attempt.
Finally, since Brady took a timeout after the Indy punt on the start of the drive, BB and company should have formulated their plan for the first offensive series (since if we made a first down the game was essentially over), including what to do if faces with 3rd and short. Then we wouldn't have had to take our last timeout before the 4th and short play, and would have been able to stop the clock.
Again, I don't mind going for it. But the way we did it was haphazard, unprepared, and inconsistent. Not a great recipe for success.
