Eh, it obviously didn't work out and defied conventional logic, but I don't know if it was an all and out dumb move. There were over 3 minutes on the clock, 2 time outs plus the 2 minute timeout. At the time, game wasn't on the line.
Say they get a stop and a touchdown, now they don't have to go to overtime. Say this miss it and get a quick field goal on the next drive, now it's a two possession game and they're done. I'm sure there's other scenarios too, which, if any one of those happened people would be on about how trying a 4th and 10 was the dumb move when there were points were on the table.
I mean, out of all the possible scenarios, an absolutely brilliant SU run game extended by one of the most heinous off sides* we've ever seen wasn't really how we would've expected the last 3 minutes to go.
*they called off sides but the pedant in me is pretty sure that was encroachment.
