Coaching is a craft in itself. I consider myself incredibly knowledgable in the NBA, its history, and basketball strategy. That said, I always wish I had played on a school team for that full-time basketball atmosphere.
In the age 20-30 leagues I play in, I'm usually the best PG of the league. It's really fun to run a team. Unfortunately, it's an amateur league. It's not like there are daily practices. It's not even close to the same culture.
Still fun though.
It's just not serious. Plus most basketball I've been able to play lately is just pick-up which is really hit or miss for good competition.
