I'm not so sure it's the freelance post tendency because I've seen Joe Johnson do it quite a bit and his post tendency for freelance is in the 20s.
Plus I think it's something I broke while I was upping all of the simple drive, no triple threat, straight dribble stuff.
When I get back to the game I'm gonna try lowering simple drive into the 20s for Bosh while keeping his attack high. Hopefully that will make him post up instead of drive when he has the ball outside of his range.
