Some great answers here! Smothering Indiana is the first thing that came to my mind. And like JJReddawg, I love seeing the former players show support. I sat a few rows behind Derrick Coleman at our last BE tournament, and his energy and passion made mine multiply. Beating Georgetown in that tournament was very satisfying on its own.
I'd also say that one of the most satisfying developments came as a result of one of the least satisfying (as is often the case with these type of things). The Bernie Fine scandal was a cloud that hung over our university, but watching our players persevere in the face of a media sh**storm, was so satisfying to me. Scoop, Triche, Fab, Dion, Joseph, Southerland, etc. These guys blocked it out, banded together, and they put the community on their backs, achieving a number 1 ranking and an Elite 8 run. I don't think I've ever been more proud of my team.
