IN MY OPINION, baseball is a stressful sport. Some frequency of injuries is unavoidable. Certain stupid actions increase the risk. Avoiding those actions helps, but you will never eliminate all injuries.
We drive cars all the time, knowing that there will be accidents, injuries and even deaths. We do what we can to limit the number, but we know we won't prevent them all. Yet we continue because of the benefits of driving.
Similarly, we play the game for the love of it. We know bad things can happen. We do what we can to limit their frequency, but anyone who thinks they know how to stop all injuries is deluding themselves.
