The will not announce the tip times for Saturday until tonight at about Midnight, but here are the times and stations that the games will be on…
12:15 - CBS
2:45 - CBS
5:15 - CBS
6:10 - TNT
7:10 - TBS
7:45 - CBS
8:40 - TNT
9:40 – TBS
By Region it would
12:15 and 2:45 - CBS
5:15 and 7:45 – CBS
6:10 and 8:40 – TNT
7:10 and 9:40 – TBS
So the 12:15 and 2:45 are the only standalone games of the day, and they are usually reserved for the best set of games from one pod.
Last year and the year before, which is as far as my research went this morning (Lundquist/Raftery/Nichols) were the announcing team for the early 2 games… they happen to be the announcers at Buffalo.
CBS would love to have Lundquist/Raftery/Nichols do their 2 standalone games (this is their best set of announcers doing Thursday/Saturday games) and if it is chalk Buffalo would almost certainly be the first set of games. I am not saying that I think Cuse v OSU and Nova v Uconn is definitely their best set of games and I am not sure anyone would really want to watch the 42-40 defensive struggle that Cuse OSU would be… but CBS decided to send Lundquist/Raftery/Nichols to Buffalo for a reason, and that would likely be to announce the early standalone games on Saturday.
By comparison, Sunday has the exactly same set of times. Jim Nantz/Greg Anthony (which is CBS’ best overall announcing crew, and their final 4 crew) will be in St. Louis, which could have Wichita St v Kentucky and Kansas v New Mexico.
Jim Nantz has also done the early games in the round of 32, on Sundays, the past 2 years.
So in summary, if it is chalk (and likely even if it isn’t chalk) Buffalo will be the first games to start on Saturday.
