That doesn't make any sense. You're basically saying that if you can run 40, ninety foot sprints @ 5 seconds each, you should be able to run 10, 20 or 30 more at the same speed. More possessions means you are getting up and down the court faster and more frequently. If your body gets fatigued,
you can't perform with the same precision. The first thing that goes is your ability to react quickly. The second thing that shows up is laziness on your help defense. Players start picking and choosing what they have the energy for. The next thing that happens is they stop moving without the ball, making hard cuts, etc. Your players/team become easier to defend. That's when the turnovers start to become more frequent. The shots start hitting the front of the rim because the legs are gone. Does any of this sound familiar from watching Fran's teams?
Your whole premise of this post is based on the assumption that only one team gets tired. If only one team got tired, why would it be the team that goes 11 deep? I don't think you thought that one over too well.
