Fake punt - this one had some merit to it, but it was poorly executed. Whalen wasn't supposed to snap it, and even Pagano was seen on the sidelines saying "why did he snap it?", so I don't put this one on Pagano. I think this was more McMahon's fault and Whalen's fault for having really bad situational awareness
4th and 2 - again, there's some reasoning behind this. Belichick was scared of Peyton, so he'd rather risk going for it with Brady than punting and giving Peyton the ball back. At least if you go for it, there's a chance you keep possession. If you punt it, you 100% give possession to the other team
Seahawks pass - once again, there's some reasoning here. I don't like the play itself, but passing makes sense as long as you pass to the corner/back of the endzone. Their goal was to save time without using a timeout, so throwing it on an inside slant was an awful idea. I have no problem with them wanting to throw a pass in that situation, but you have to throw it to the back of the endzone and put the ball where only your receiver can get it.
Falcons - this one makes absolutely no sense to me. The only thing I can think of here is the element of surprise. The Falcons got greedy. I don't pin this one on Quinn, but on Shanahan. I see no reason to be throwing the ball in those situations. Plus, add in that this was in the Super Bowl, and that they were up by 25 points. This is by far the worst one on the list
