Mister RX, if the Round of 64 these past two days are any indication, those times may be generous.
There have been a record six overtime games in these two days (and there were only two such games throughout the entire 2012 and 2013 tournaments). And you can count on one hand, literally, how many games were not close (four of the first 31 as I type this and the last game in San Diego is about 6 minutes left but isn't a blow out, either.)
So people need to monitor the situation, and I promise to post as we get close to the normal TAR air time on the east coast feed. The local station for me is the "local" home station for one of the teams in the Iowa State-North Carolina game which is the last one on CBS that afternoon, so I will not be able to avoid knowing about any runovers in the tournament.
