I think it is hilarious how many State fans have reacted to Amile's decision by suggesting that he's going to be the next Lance Thomas.
I know they think that's a negative, but if Jefferson's career matches Thomas -- 101 starts in 140 games for teams that averaged 28.8 wins a season, won two ACC championships and was the starting forward on a national championship team ... yeah, that would be okay.
Seriously, I think Jefferson is a lot like Ryan Kelly of Duke and/or Milton Jennings of Clemson -- both were (like Jefferson) McDonald's All-Americans ... both were (like Jefferson) too-skinny-power-forwards who had to put on weight ... both played little as freshman, started to contribute as sophs and were very solid ACC players as juniors last season (and, I think, will be two of the best power forwards in the ACC next season).
From what I've seen of Mr. Jefferson, I would expect his career to follow a similar track.
PS As for his real size, I too have seen everything from 6-7 to 6-9 and a wide variety of weights listed. But I think it's significant that Duke's press release listed him as 6-7, 190. Until Duke changes it, that's what I'm going with.
