If the goal is to go pro, I'm not convinced that Kentucky is better than being a star at ISU. In fact I think he's better served to do his 2 remaining years here and then go pro sooner, i.e. sooner than waiting one year and then doing 2 years at KU.
And Cy13, you're more than hinting that all the defections, including this one, are about the coaching staff, and certainly you have insight into the players' thinking, and that counts for something. BUT on the other hand, I keep thinking that McD is a guy who's won everywhere he's gone. And IF Wes would have returned, he would have won at ISU next year too. (That's no knock on Rahshon and Jiri, but more about us having returning guards with experience.)
And if it's about happiness, of course he was unhappy playing hurt all year long with everyone questioning his toughness, and losing on top of that. Who wouldn't be unhappy. But that's not about ISU, it's about a broken foot. And it would've happened anywhere.
All of which makes me think this: dude, you're making a bad decision! But alas, we're all prone to thinking the grass is greener, even when it ain't.
