One, that is sick
Two, it is sick but makes sense.
I can still do 42 on a good day when my legs are fresh. My vertical has dropped to about 24 from 34-36 when I was in my prime, so SUFANDU, I feel your pain...
This implies I am bringing my legs up 18 inches to clear the height...
His vertical, according to a scouting site I saw was 40 (which is sick). I bet it is higher now but, given that he is a couple inches taller than me, it implies that a 60 inch box jump is doable with a low forties vertical.
Unreal what unbelievable athletes these kids are...
