I think I read both MBB and WBB tournaments have crushed TV ratings records this year. The peak of the tournament for me though is the first weekend, followed by the second weekend. By the time we get to the Final Four, I'm usually basketball'd out and more focused on the Reds anyway since the regular season has started. Same with college football. I hardly ever watch the playoff games, especially the Monday night finals which feel anti-climactic.
I wonder how a potential Sunday afternoon South Carolina-Iowa WBB final on ABC would compare with a Monday night MBB final on TBS.
