I watched a lot of this game, and I got the distinct impression that a lot of the rebounds they gave up, loose balls they didn't get to, etc. was a result of not trying to get hurt during a preseason game.
If Maxey wants to go balls to the wall in order to convince the organization that they can roll without Harden, giving him a starring role, fucking let him. No reason to risk the season to prove any points in a preseason game. Get some conditioning in, get to know your teammates and move on to the next. That's all I want out of this, and frankly, all I want out of the regular season.
