The refs' hands were tied, but I guarantee you college adds in a 10 second run off rule. After the LSU game, they had no one to blame but themselves for having about 14 men on the field for that last play which gave LSU the untimed down. But here, they kinda got a rough break.
And I was wondering what would happen if that were the NFL. Does too-many-men-on-the-field get a 10 second runoff? I thought any procedure penalty would get a 10 second runoff but as we all unfortunately learned on Christmas, that is not the case.
I think both college and the pros will move to a 10-second runoff rule for any penalty taking place pre-snap or at the snap (with, of course, the option to call a timeout instead).
