It's so weird, and frankly lame, that 23 year old juniors in college are so widespread.. For all the blame that gets thrown at AA;U ball, you've gotta be really good to play above your age....
In college we have the inverse happening, if your kind of on the fringe, not quite good but not bad enough to write off, they'll let you stick around til your 24 to prove it vs teenagers...
Thats weird AF to me...
