Most of that time was taken by the refs reviewing that patently obvious wrong call they made when the OK guy dribbled it off the Baylor defender's foot, but the refs called it off OK. Tight game, wrong call, they HAD to see that on the replay, but they didn't have the onions to reverse themselves in front of the home crowd. So they watched it over and over and over again, hoping it would somehow go away, but it didn't.
Kudos to ESPN for switching Sports Center over to a live feed of the game, until the OK-Baylor fiasco ended. There's a lot to criticize about ESPN, but I give them credit for that move.
