Obviously, the two situations are completely different
I'm not so sure. I don't follow Euro ball and don't claim to have a sense of which players really aspire to come to the NBA and which just have it idly in the back of their minds. Tiago Splitter chickened out on the NBA so many times that I predicted he would never actually do it (which proved out to be wrong) and that, even if he did, he would not be an impact player (which proved to be correct).
This board was very excited about Vujanic when the Suns first acquired his rights. People proudly laid out their projected rotations, three-deep, with Vujanic slotted in as part of the future. Gradually it started to seem that he might not come to the NBA at all, and so this board -- which, on the whole, has a perpetual "Buy high, Sell low" philosophy -- decided that maybe it would be better instead to trade his rights. Even before he got hurt, Vujanic's prospects for coming to the NBA got dimmer and dimmer, which increased the chatter of how the Suns might salvage anything of value from their ownership of him. And then, yes, as SirStefan said, the jokes continued once Vujanic's career was over.
So far, the Bogdanovic situation is a perfect match.
