Well Steve, I've been transplanted all of my adult life. So many people who live in Wisconsin were also born and raised here; just the opposite of my last adopted home state, Colorado. So, while I don't often find myself rooting for the local teams, I'll have to cheer on Marquette now, even though they knocked out my son's Tigers.
(By the way, if you're watching a Missouri home game on TV next season, and they show a young man in a yellow suit with a tiger print tie screaming his head off, that's my son. He was a CBS "fan of the game" at least once this season. Unfortunately we don't get the feed here for many of those contests.)
I do root for Marquette when they aren't playing one of my favorite teams, but my other son is looking into Saint Louis University, a member of Conference USA. And since I'm a Illinois alum, I can't bear rooting for another Big Ten-11 team.
