Actually i agree with him. 80 may be a tad high, (i run with it at 70)
but i just don't get the sense that fast guards are actually fast with game speed in the 50's. Also, sometimes on plays the players WALK to their spots coming off of screens and such. At a higher speed the players seem to hustle to run their plays more. I suppose its all a preference. BTW the scores aren't higher because of the speed.
