Barring injury, I don't see any "bust potential" in Lydon -- at all. Keep in mind that even though he was a year younger than all of these guys, he played on that Under 18 Team USA squad that featured blue chippers like Tyus Jones, Justice Winslow, and Stanley Johnson [among others], superstar recruits who were older and had already completed high school.
Lydon led that team in rebounds and minutes played, even though the three players above are all projected as lottery picks. Think about that for a second.
Like we've both stated, I expect the usual freshman growing pains as he gets his feet wet, but this kid is going to be terrific for us.
