Why basketball?
I understand the movie contrasts how awful he was before and how awesome he gets after the wolf.
But, to make sense of the world the movie is set in, why on earth would a midget pick basketball as his sport?
I understand the fat guy, he would probably suck at anything, but a short guy like MJF would excell in many other sports that require small stature. Why go for something he's certainly gonna suck at? Here's a list of better ideas:
gymnastics
figure skating
diving
table tennis
equestrian
Imagine the wolf riding his horse towards a slam dunk, that would be just a smash hit!
