MLB - Red Sox. Grew up in MA. Thats is where my folks are from, and every last one of my relatives live. Grew up watching them play.

NBA - Celtics

NHL - Bruins

NFL - Detroit Lions. Got sucked in as a huge Barry Sanders fan. Also spent some of my youth in Michigan. Just never got into football until later with the Celtics and Bruins winning everything as a kid.

College - University of Florida Gators. Spent 6.5 years in Gainesville as my wife got her masters there. Seeing as every dollar of my paycheck was going there, I kinda supported them.
