Basketball, when played at its best, at its highest level, is a very physical game. And much like in other highly physical games like football and hockey, the physicality even when playing within the rules, sometimes causes injuries. You simply can not make illegal all parts of the game that are physical simply to stop the possibility of injuries.
Blocking and tackling in football is a physical part of the game that can cause injury. Checking in hockey is a physical part of the game that can cause injury. Yes, there are very blatant types of these acts that are against the rules set in place to prevent injury, but they are easily seen and easy to enforce
Diving for loose balls is a physical part of basketball that can cause injury. And I believe there are very blatant forms of this act that can easily be seen and punished with flagrant fouls. It doesn't happen often, it's extremely rare, but it does happen and is punished.
Last night's game was an example of a clean dive for the ball that got someone injured. It happens. It's part of the game because it's a physical game. Trying to eliminate this part of the game is not in the best interest in how to teach the game, develop players or increase the enjoyment to watch the game.
Injuries are part of the game as they are in every physical sport. You play these games the "right" way and injuries are still going to happen. As a player and coach, you have to understand this and just live with it.
There is no reason to outlaw this portion of the game. It's a passionate play that can change momentum and alter the direction of a game. These plays are essential to basketball. You do not make them against the rules of the game.
