Coach O's answer about it was confusing also. He said something to the effect 'we try to run it out and score and if we can't score we take a knee'. They could've scored twice and never took a knee. According to the announcer Bower was looking towards the sideline before the final play signaling with his arms 'TD or not?' and then they ran the RB dive to try and score. Weird.
At first the announcers thought it was stupid for him to slide rather than score, not knowing Arkansas was already out of timeouts they said 'you want to go up by two scores I don't know about that'.
Was just a bunch of people all around that didn't know what was going on or should go on. The only smart one was RB #4 who was just trying to end the game with the ball in his team's hands rather than having to out and put their D on the field again.
Oh, and I had Ark +13! I feel very fortunate! Also had USF +14/16 ~ another fortunate outcome the way it ended up.
