I get your viewpoint but I think in the long run having more local guys who played at MN be around the scene, the better. I don't think Chet ends up at Gonzaga if not for Suggs.
For example, lets say Suggs went to the U and left after one year. We would have years of Suggs being an NBA player and former Gopher hanging around the circuit. We'd have a group of 8th graders who idolize Suggs who would be watching him play at the U. His dad would probably a bigger fan of the U.
There is all of this and I think these types of players will definitely lead to more wins. We need to get those wheels rolling and anything we can do to help that process, I'm all for.
Lastly, as far as Rickert not helping. I think his legacy is a little underappreciated (likely due to unrealistic expectations). The year before Rickert was on campus, we were 5-11 in the Big 10. The year after he left, we were 3-13 in the Big 10. His two seasons? 9-7 and 8-8 respectively. He helped bring us out of an absolute dumpster fire.
