William Had Alot Of Talent....
....but knee injuries wreck many athletes. It's the nature of the beast. Very doubtful he'd have ever made the NBA even with 2 good knees but he would've been a top shelf player at a good school like Marquette and probably made good money playing overseas. Once the knee went, show was over. Unfortunate.
As for Arthur Agee, he was never quite the talent that Gates was, nothing can be done to change that, just a shame he had such a deadbeat for a dad, but of course there's nothing new about that story either.
Knee injuries and deadbeat dads go way, way beyond this documentary. The only difference between these kids and THOUSANDS of others was they had cameras following them around.
