Al might have some kind of social anxiety disorder. I grew up with a few people like that who could barely talk to anybody they weren't familiar with without sweating up a storm, but they were pretty good ball players because they were expected to sweat on a basketball court and didn't have any insecurities because of that.
Whatever the case, it's kind of funny that Mr. Dunk on your face is camera shy. Endearing to me.
Dude was talking fine, he just sweats, some people sweat a lot. If anything, being a heavy sweater helps your game, people dont want to body you up. and you can spin off people easier
