I learned today of a new college football rule to take effect this year. Under the old rules, the clock was stopped after every first down and didn't start until the official placed the ball on the ground and then backed off an blew the whistle. Under the new rule, the clock will start at the moment the official places the ball on the ground.
Somewhere, a quarterback will be oblivious to the rule change.
Edit: I may have to back off on this since I could be wrong. There is a rule change but I'm getting conflicting info.
