This is slightly complicated. I was raised a UCONN fan (dad is from CT and grandmother worked at the university), but they are not in it this year. I'll root for any of the Big East teams. The one exception is Maryland since I got my MBA there. Typically my motto is ABD - Anyone But Duke!
Now this year Vermont is in it and I spent the first 22 years of my life living there, so I'll have to root for them. Has a 16 seed ever upset a 1 seed?
