I don't think it has to do with a coach saying "Hey kid, don't go to KSU".
Probably more of a "KSU coach wanted to stop by after practice to see a kid but I told them we didn't want any distractions before state but its totally cool if the mizzou or KU coach wants to stop by"
I think this is plausible.
Also, hasn't Wier always been pro-KU/anti-KSU? I know we got Sproles, but other than that, I think he was always a very pro-KU guy. And even then, if the old stories were true, he was pushing KU hard to Darren.
