Around tournament time, I always hear people say "It's hard to beat a team a third time". I decided to see what kind of data I could find. Since the 2000-2001 season I found 39 cases of one team beating another twice in the MAC regular season, then playing a third in the MAC Tournament. The team that won both regular season games is 32-7 (.821) in those third games.
I posted this on the MAC board as well, and someone asked when one team was an obvious favorte saying it was tough to beat a GOOD team three times. I'm not sure how to quantify GOOD, but...
When both teams were .500 or better in MAC play, the team that won the first two games was 11-3 (.786) in the third.
When the two teams were withing 4 MAC wins of each other, the team that won the first two games was 15-4 (.789) in the third.
