Tom Crean and Bo Ryan have long been bitter rivals. The rivalry goes back to Crean's Marquette days, when the two coaches faced off once a season. Nowadays, they typically play twice a year. And since Crean came to Indiana, in 2008, Ryan has owned the rivalry, to the tune of a 9-0 record. The latest win came in Tuesday's upset at Assembly Hall, and neither coach seemed overly excited about greeting the other in the postgame handshake line. Watch the ultra-quick handshake now.

Admittedly, it's just a handshake. For all we know, the two coaches could have exchanged pleasantries before the game or after it, when the cameras weren't around.

That said, it's not every day you see a handshake as quick as that one. Plus, it got basketball fans' attention.

The two won't meet again this season, unless Indiana and Wisconsin face off in the Big Ten tourney or NCAA tourney.
