Chris Borland has had 30 concussions. I'm glad he retired. Football is a dangerous sport. We all know that. Now we know it's dangerous for various brain injuries. A trend has already emerged, players are retiring earlier due to concussion concerns, etc. If Borland helped raise awareness then good for him. His crusade to end football though will fall way short. Coaches, players, and fans love pro football. Most importantly the owners love all the money they are making.
