In my opinion, that is what is wrong with this line of thinking. It is essentially "Tyus or bust" type of thinking.
Your line of thinking is essentially that you think Tubby should do this, lock up Lockett and Mbakwe, and we'll finish in the top 3-5 of the Big 10 and maybe make a run to the Sweet 16. Because of our Sweet 16 tun, a guy like Tyus will look harder at the U and stay home.
I agree, if all that happens, and Tyus is good enough and stays long enough to make us really good, it all works out. Then "cutting" Mav and Chip was all worth it in the end. When you run the cost-benefit analysis, it validates the decision.
However, there is a really strong possibility that a lot of those "ifs" don't happen. Gopher basketball will continue with or without Tyus Jones.
For me, i've always thought Tubby's strength as a recruiter was his name and the idea that he is looking out for what is best for the players. I think he is seen as a high character guy. I think if multiple stories start circulating that Tubby was cutting players, I think his stock drops a little bit. It probably won't affect him with homerun recruits like Tyus or Vaughn, but it could certainly have an impact with out-state recruits who aren't as highly recruited as both Hollins or Elliason. I'd imagine people would be less pumped up about last year without Andre Hollins.
