Apparently the coaches saw some things that cooled them off.
The assumption upon which you are operating is that he went to Wisconsin because NU was disinterested. Is that a valid assumption? How do you know this. Is it not as likely, or more likely that the kid just thought Wisconsin was the better program (at least for him)?
You think that NU would rather have Zimmerer than Lechner? I find it hard to believe that NU did not want Lechner. They just did not compete well for him. If NU is willing to take recruits from in state that others were not interested in surely they would want the in-state players that were attractive to outsiders as well.
If we cannot convince the best players in the state to stay, well then..... we ar in (stating the obvious) bad shape.
