As far as these 1 seed upsets in a "normal" mid major conference where you have 1 maybe 2 teams which are far above the others in the league then 1 seeds going down is a big deal.

The MAC however entered its tournament with the #1 team having 4 MAC losses and the #2-#6 teams all sporting 5 MAC losses. The #1 (Toledo) really wasn't even the favorite due to the long track record of not getting it done. Buffalo while the #2 seed has track record in the MAC tournament and is the most mature of all the programs.
I can remember back when whomever had the senior guards won the MAC tournament but now the MAC really has "programs" and basketball coaches in the MAC stick around generally much longer than they due in football. Buffalo has lost coaches for a very high level of success and Ohio has 5 HCs since 2008 but this is not typical of the MAC.
You can see the programs just by looking at who has won the MAC since 2005.
Buffalo (4)
Ohio (3)
Akron (3)
Kent St (3)
They've collectively won 13 out of the 15 past MAC tournaments and are always in the mix at the top of the MAC. These 4 schools are closer to Cleveland and have the ability to bring fans to the conference tournament. Toledo while not loaded with banners is usually pretty good too. Bowling Green has a new arena and its helping them.
On the program side for example John Groce was the coach at Ohio for a couple of those tournament wins and is now the HC at Akron. He and Boals at Ohio are the too highest paid basketball coaches in the MAC so this conference history to it. Rob Senderoff has been at Kent St for 10 years. Tod Kowalczyk has coached 11 years at Toledo.
MAC basketball is on the rise. Better coverage since the realignment and the second tier schools are bringing in higher caliber coaches. Salaries are now higher on average than the MVC. NIU hired an assistant on Bobby Hurley's staff from Arizona State. Don't have the salary info on that hire but probably close to 500k.
Getting back to tonight's game I like Buffalo with a competitive 8-10 point victory tonight. Ohio though is a hot team having won 8 of 9 going back to January so anything is possible but that one loss was to Buffalo at home. Ohio also has a track record for winning the MAC tournament as a lower seed (did it one time as a 9 seed) and the last time was a #3. Seeds as you can see aren't as important as other conferences.
