Rasho is apparently one of the more lively guys in the locker room and a real practical joker when the cameras are off, but he hates giving interviews with a passion (at least, he did in Toronto). His accent is thick, he seems to find most questions the media ask him being not particularly insightful or intelligent. But Rasho is a pro all the way: he just wants to play ball and he'll do quite well for you.
I don't think he's unhappy to be in Indiana at all. He should be fairly excited, the way he finished the year last year and that carried over into the Olympic qualifying tournament. He knows he's going to start and has an opportunity to play for a new contract. Plus, he's now working under a real coach - he'll be happy.
