It's obscure because it aired on a sports betwork and is a weird beast of a show. It didn't draw in adults because, why the fuck would you watch a sports channel for cartoons? It didn't draw in kids because most kids don't care about soorts, or rather, two adults yakking about sports.
Then there's the show itself. I've only seen a bit, but it sseems like it doesnt pursue any real explicit content, so it's just bland and boring for kids and adults alike.
