Too Many Key Injuries in Pro Sports

I have been watching the National Basketball Association playoffs off and on so far during their first round and find the games usually competitive and interesting.  There is one problem, though, that starkly stands out: the tendency for there to be too many injuries, especially of star players.  I can't keep up with it anymore, and there's no telling how a series will go when a favored team, successful largely on the backs of its greatest talents and achievers, falls victim to their injuries during a series with an obviously inferior team.  This has been going on for years, but now it seems that we have the most fragile athletes ever.  The sport of basketball and others...not just football but also even tennis and golf...are played on such an extremely high level in our era with very little margin for error: everything has to be done all-out...every possession, down, point or swing...depending on the sport...must be tackled with the athlete expending all the energy they can produce and straining their bodies to the limit and beyond to avoid being beaten by the opposition.  Name me a series or tournament in which its complexion hasn't been drastically altered due to several key injuries...no, getting hurt is now the rule rather than the exception.  Although the games themselves may still be close and exciting to watch, the ultimate champion...due to the many injuries we're seeing...is often a team or athlete that essentially prevailed by default.  The result, I think, is a general cheapening of the sports and their championships...
