But that's where you're incorrect. You do indeed have to run, because if the ball lands short or where you aren't, you have to run to go get the ball and have a chance to win the point. And, as you stated that you don't have to jump, you actually do, if the ball is to high to reach from where you are standing. For example if you're at the net and the player hits it above your head, you would have to jump to try to get the ball, or run back quickly to hit the ball. Or if you're in the back and your opponent hits it high and it bounces above you, you would have to jump or run back near the fence to get the ball and hit it back.
You make a strong point... But in the game of basketball you make decisions that you think will benefit the team. Your constantly making quick decisions and if its the wrong decision your not just putting yourself at a disadvantage, your putting your whole team at a disadvantage. Now in the game of tennis i know there are doubles teams but your only affecting 1 other person and not a whole bench full of players.
Well, if you're on a team of players, such as a program like how it is in Champlin Park, there is a team, and if you decide to lose on purpose, you actually can end up losing the match for your team. And in tennis you constantly make quick decisions as well, such as where to hit it, how hard you hit it, how high, or backspin or front spin. If you end up messing up, you are putting yourself at a disadvantage as well since you possibly be down in points.
