You can't teach height or heart is a very true statement. 6'4" didn't get that high off the ground either. Just because you're tall does not mean you can jump. There are a lot of players 6 feet or taller that can't dunk, while others like 5-10
Shakayla Thomas recently of Florida State can easily dunk. Don't forget that 5-7 Spud "I got hops" Webb once won an
NBA dunk contest. Having "hops" is a gift.
Gabby Williams (my girl) is 5'11", but can out jump most players 4-5 inches taller. You either have it, or you don't. The only "hops" you can purchase over the counter is in beer.
Cheers!
