Lack of youtube videos = bust
Now, now. I never said that. My point was that in this day where every thirteen-year-old kid has a YouTube video with a collection of his dunks, this particular video from Motiejunas has a remarkable number of shots of him running lay-up drills in practice. That doesn't mean he's a bust, but I think it at least raises the question of whether he has actually done much up to this point. That particular video does not have "superstar" written all over it. I'll leave the boom/bust pronouncements to those who have actually seen him play.
(BTW, I've looked at his stats in Treviso this year, and it seems that he's scoring OK but not rebounding very strongly, but I don't know how to gauge that because it's a totally different league.)
