Used to be that the chains had to be set before the clock started. If that has changed, is there a separate official who is there to mark where the chain should be set?
That's NEVER been the case. That's what announcers say and people assume it is the rule. One thing has nothing to do with the other. Clock stops due to a first down; clock starts when the Referee winds the clock as soon as he determines it is ready for play. Basically, it is when the Umpire or Center Judge has the ball at or near where the spot will be and has spotted it or will be putting it down soon. As long as he's consistent the entire game, there shouldn't be a problem. Those complaining on here about t.u.'s last drive MAY have a point but only if they can compare it to how the clock was wound on the previous KU's drive.
About 12 years ago, the NCAA went to the 40 second play clock. Prior to that, every play had a 25 second play clock where the Referee whistled the ready for play with either a wind the clock or a chopping motion (game clock remains dead). Now, the 40 second clock is already running because it started at the end of the previous play. The reason the change was made was that it was felt that there was too much inconsistency in how much time elapsed before the Referee signaled the ready for play.
KU needed to make just one defensive stop on that last drive and didn't do it. That's why they lost.
