The one question the NCAA really must ask is this: if Kanter werenít committed to being a collegian, why would he be here? Thereís plenty of money available to him to play for Fenerbahce or another club. Heís gone to an awful lot of trouble to play college basketball. To be a pro, heíd merely have to return home.
That's a bit naive of a take in my opinion, obviously Kanter has a lot to gain from playing for Kentucky(incrased marketability for his NBA draft stock) and the fact that whatever team drafts him won't have to go through the whole Rickey Rubio situation.
Now as you pointed out the guy at Fabernace has all the reason to trash him, he's never going back to that club, on the flip side though, Kanter has every reason to lie if he did take additional money.
So that leaves it to the NCAA to investigate and if they find enough evidence to declare him ineligible. In all honesty, the Turkish team needs better bookkeepers, you'd think it would be pretty easy to point out exactly how much they've paid him.
