Are you being sarcastic? If they did it on every kick, they would stand no chance to recover it. They had a chance on that one play because WV wasn't expecting it. Unfortunately, it was executed very well, particularly by the kicker.
I'll say it again. OU's defense is not stopping WV. They aren't going to stop them. Stopping them a couple of times at the start of the third quarter is not evidence to the contrary. Either aggressively go after points or lose. The onsides kick is going to be the difference between losing by 10-14 and losing by 17-24. It's still a loss. I'd rather just try to win.
