i used to play hockey and skate with a guy by the name of gilbert brule. drafted sixth overall in the 2005 nhl draft.
he was the best at skating out of the bunch, and spent the least amount of time skating due to playing a fucked amount of hockey. he had to give it up when he got signed to a junior team, but he would've been incredibly good at skating today if he'd been able to continue doing it.
i fully back the theory that athleticism caries over very well into skateboarding.
