I can't think of a better opponent to learn from than European teams. They have widely different styles of playing, and all European teams are much better than they were 10 years ago. Kansas can only learn from these teams, and will certainly improve their defense to take on dynamic and diverse teams in the regular season. I always wondered where those teams stay while traveling around Europe. I believe they were in Interlaken for a game, and I wonder if coach rents out an Interlaken hostel for them or if they just sleep on the bus. Their basketball team certainly bring in the most money for their school, so I can imagine they have an athletic budget to be treated like royalty.
Regardless, I think playing European basketball is a great idea for Division 1 teams. It will make US college teams better and make basketball even more popular in Europe.
