Reggie Bush of the New Orleans Saints lies injured on the ground during a game against the San Francisco 49ers during an NFL game at Candlestick Park in San Francisco, California.
It’s been a tough season to be a star NFL player: Philadelphia wide receiver DeSean Jackson and Atlanta defensive back Dunta Robinson both left with concussions after hitting each other on the same play last Sunday; a Pittsburgh Steelers linebacker sent two different Cleveland Browns players out of the same game with concussions. These are just some of the most extreme cases of what is shaping up to be the year of the concussion in the NFL, where players are dropping every week with head injuries. The NFL is under pressure to stop ultra-aggressive hits, but half the fun of watching and playing football is witnessing, and dishing out, big hits. While the NFL is higher profile, these same problems plague hockey in the NHL which has also seen several star players missing extended periods of time with concussions. If the violence that is a key part of your favorite sports was doing permanent damage to your favorite players, would you still watch?
