Don't quite understand what you mean by situation like Biggs.
The reason he isn't getting any offers isn't because of talent. It's because his grades aren't good and most schools need to see if he'll qualify.
You mean like Biggs out of high school?
I think part of it is his height. I think tall dudes struggle more than little dudes to get arch on their shot.
Doesn't mean it's not fixable, but it's probably been something he's struggled with for a while.
