My understanding is that it was to help prevent further unbalance of the schedules. UConn/ND would have a game against the upper tier and one against a lower tier. Most likely wouldn't effect UConn either way. If you're the 3rd best team, but your repeat games are against #1 & #2 you could end up finishing with 4 losses and a 5th or 6th BET seed. Most leagues play a home/home type schedule so you get an accurate final league ranking. Two years ago ND lost on a last second basket at DePaul which combined with 2 losses to UConn dropped them to the 3rd seed in the BET. DePaul had lost to UConn, Louisville, and Marquette and kept the 2 seed on tie breakers. Similar to how St. Johns got the 2 seed in the BET last year. UConn's schedule was more difficult.
