Geno recently commented on Mir McLean saying that she has a higher vertical leap than any player he has ever had. This sort of floored me as Gaby was a world class leaper.
Gabby could do the Fosbury Flop over a bar a little more than 6'2" off the ground. Geno's statement, which may include hyperbole, refers to jumping straight up.
I've been Mir a couple of times in person. I'm not certain whether she can dunk or not, but I can tell you that she rebounds well above the rim and gets up faster than anyone not named Gabby Williams. Mir is very exciting to watch. She elicits lots of oohs and aahs from the spectators.
I would love to see a contest in terms of who can touch highest on the backboard among Gabby, Aubrey, and Mir. Aubrey is 2" taller and longer, so she may have an advantage, but Mir and Gabby just explode off the floor. Check out Mir's videos.
