I heard that David Robinson was only 6'2 when he went to college. So he grew almost a whole foot since college. Lebron does look like he's 6'8 though. But did anybody see him stand next to Yao. Geesh, Yao makes him look like he's 5'10. I would post the image, but the image posting thing still doesn't work.
I read the article too, and it gave me shivers. I don't think its like the Kobe Bryant thing, since I remember that: people were just saying that because he was so young, it was likely that he would grow(and he did, that one inch). But the article has Bron quoted as saying that his doctors told him that genetically, it was quite likely that he would sprout to 6' 10. Of course, Bron is also a lot more built than KG and Kobe were, and that extra weight lifting to maintain that physique might stunt his growth(though at this point its not that big a deal).
