To reduce injuries, NBA should seriously reconsider shortening regular part of the season. I know that money is always an issue, and owners and sponsors are worried that they would loose too much money, but what we have now when top players are dosing their playtime during regular season ain't fun either, so many games look like exhibition.
And we all know that real stuff starts at playoff, so in the end we would have more interesting regular season, and healthier players in playoffs. Win-win situation.
There is no need to lower the NBA games. Why? It's because injury is always there to happen. What gives if we only low the stretches, yes NBA will lose money but these players are enjoying their jobs. They can get fame, money and happiness in one.
The only thing about injuries is to have a good physique. Just look at people that having injury most of the time. The unicorn, Kristaps Porzingis, he's injury prone. He's slim and he's big that's why he is injury prone. If you're big, the best thing to do is to build your body and put some weight to avoid injuries. Injuries are like accidents, it may happen all the time. Even during practices it may occur.
