timeout occurred and they ran off time during the play. Great question about what would have happened if Oregon put 20 guys on the field and just told the ref they were ready for play. It does become a free play for the offense but what they can realistically do if the defense has 20 guys to defend?
Basically guarantees a clock run off with no gain for OSU. They will have to change the rules to allow for the other team in that situation to put the time back on the clock.
