Much easier in my opinion to teach defense or scheme a defense, than to make someone a good offensive player.Defense isn't the primary trait they're looking for in a center. In fact, it may be 5th at best if you're putting together a top 5. Doesn't crack mine.
High BB IQ - Need to be able to see the floor and anticipate what's going to happen.
Playmaking - Need to be able to execute off what you're seeing.
Shooting - Need to be able to shoot from deep to drive spacing for system.
Scoring - Need to be able to get a shot on your own when shit breaks down.
Consistency - Need to be able to do all of those things consistently.
Then I'd put defense into the picture but I'd still probably put it behind intangibles.
The goal for the Hub 5 is to essentially produce plus points versus what you'd give up defensively. If you can account for 30+ points in a game between your own production and what happens off your playmaking, it is very unlikely you're a liability unless Wilt is out there on the other side.
