I was going to say the same thing, going for 2 points there made no sense, and yeah the play call was stupid. If they were only down 3 instead of 4 that last time they got the ball, would have put more pressure on our defense to not let them in FG range. With a 4 point lead, I felt pretty good about us not letting them get a TD since they aren't a high powered passing attack.
Then they got a delay of game on the last drive too. MSU fans must have been going crazy with some of those decisions and the way the end of the game played out.
