The lapse was not twenty seconds, but the ref watched the play in real time with no flag, the QB rolled around as if injured and the flag came late, say five seconds. Of course the QB jumped right up and did not miss a play. Then, in OT Sims gets hit late, there is no immediate call, and no late call when in fact he was injured on the play. The moving of the chains when Duke was clearly short and it should have been fourth down was awful. Refs do that too much today - quickly moving the chains at a glance without taking close looks and measuring. If I have to sit through three minute timeouts for media, I can wait for the refs to get first down calls correctly. Finally, the ref monitoring line play on the final drive might should have looked for holding instead of locking in on whether or not he could give Duke 15 with a hands to the face call. Their right tackle, #55, held egregiously on at least four downs in that drive.
