I don't know much about either team, but I can see going for two there. You would do it for one of two reasons:
1. You had a play that you thought had a greater than 50% chance of working. Since the odds are something like 40% to 45% in college generally, it's not a big stretch to sometimes just believe you have a play that will tip the odds in your favor.
2. In OT, your FG kicking becomes disproportionately important. If you think the other team has a big advantage on you in the kicking game, I absolutely can see taking your shot there and winning or losing on a 2. If you go back to the game we lost in Raleigh to NC State when we still had Orlovsky, I absolutely thought we should have gone for 2 when we tied the game with a 1 with about 3 minutes left because I didn't like our odds bringing out Matt Nuzie in that environment on the road in OT.
I was watching. Most coaches take the 1, and that's the safe play. But I don't view it at all as flat out dumb -- it depends what his reasoning was.
