Injuries are always contagious, once one player goes down, the next one follows suit.
In the NBA, it is often the case that you stay healthier the healthier you are; once an injury occurs, they tend to follow one after another.
Because in such a high-intensity league like the NBA, injuries really are contagious.
When a player goes down, especially when he is a key part of the rotation, it means increased playing time for the other key players.
Increased playing time leads to greater physical burdens, and the risk of injury for healthy players also increases.
Once a second player goes down, the remaining players' burden further increases, and the risk of injury escalates.
If not managed properly, this can start a vicious cycle where players keep getting injured before others have recovered, leaving no one available to play.
