Don't put much stock in Stu Whitney's writings. If you read his stuff regularly (then you have a much higher pain threshhold than me), you will conclude he's just a pot-stirrer. You should assume he's regularly reading this message board to see if you're talking about him.
Cody Larson is a very talented kid and people haven't yet seen what he can do on a basketball court. The prior coach was criticized by lots of people who know something about basketball (I love to watch it...don't know the fine points) and I think some of the criticism was accurate. For example, couple years ago Larson's high school team included a very talented football linebacker (Preston Evans, playing very well for North Dakota State). The coach had Larson setting screens for the 6-1 Evans. To a fan like me with little knowledge about the fine points, I thought that didn't make a lot of sense. The prior coach went through several years with excellent talent and couldn't do much with it. The parents at that high school were pretty upset. I don't think it was "Larson's people" going after the coach. There were a lot of people going after the coach much like what happens in many small towns.
Larson's had his share of problems I suppose, but I don't think there's been anything that should scare off a school. A coach will just have to lay the law down and help the kid reach his full potential -- the potential is very good.
My connection? None. I am an SDSU fan...wish we could have gotten Larson. I live in a town which regularly plays SF Roosevelt in sports. We regularly beat the Roosevelt BB team and probably shouldn't--they have more talent. We have a better coach.
Don't let the rumor mill, Stu Whitney and the yo-yo's who write anonymous comments to a newspaper blog scare you off. Iowa's coach will have to have a serious talk with the kid to find out what's going on but this kid's got talent and he's not a monster.
