I am so sick of people mentioning his weight like he is going to be playing at 206 lbs for his entire career and is never going gain any additional mass. First of all he played last season at Kentucky at roughly 225 lbs (keep in mind he was just 18!). He lost the weight because of his knee and he has plenty of time to keep putting on more and more good weight. Kevin Garnett is about the same height and he has played a majority of his career at around 245 lbs. I am confident that a kid who just turned 19 and is still physically growing can add an additional 20 lbs or so from his 225 lbs playing weight from last year.
It's because 206 pounds at around 7' tall is pretty jarring, whether you're talking about a healthy pro athlete, a currently injured athlete, or a starving Samalian. I don't think bringing it up as a concern is just completely outrageous, even accounting for the weight loss since injury. I think he's the clear cut best prospect in this draft and I hope the Cavs keep the pick and take him, but that definitely represents at least some concern I have about him, especially given that we've seen him get out-muscled by thicker opponents in college (as I've mentioned before, by Patrick Young, a skill-less dude with an excellent NBA body).
This was a concern even before the jarring 206 number. Way back when, the board discussed a photo of him standing next to Anthony Davis and the difference in shoulder-width was pretty drastic (in favor of Davis). And while teenagers tend to put on weight and strength, almost across the board, there are some examples of guys who just never really bulked up the way they were projected (or hoped) to. Anthony Randolph is an example that's jumping out at me at the moment.
All that said, I still want him because I think he'll be an extraordinary defender and an absolutely disruptive presence even if he doesn't pack on weight. He's quick and explosive and long as hell with great hands, great instincts, and a great motor/attitude. If he adds significant physical strength to his game as he matures (which I agree he very likely will), we're looking at an all-around, game-changing, needs-to-be-schemed-against, monster of a defensive player. If by some small chance he's just always vulnerable in the post against bigger back-to-the-basket pivots in one-on-one situations, and that's really his one defensive weakness, fuck it I'll still take it if he's as disruptive as I think he'll be in all other facets of defense.
