These either/or solutions won't cut it. Obviously, the NFL can't cut its throat and allow rules to prevent injuries. I think what probably can be done is outlaw the helmet-to-helmet and other truly viscious hits now so common, even though helmet-to-helmet was supposedly already outlawed. There's no way cumulative lower level trauma can be factored into preventative rules. As in so many situations, common sense will eventually demand a solution without taking out the normal violence which fans love and crave. The only thing we have to guard against are the "do-gooders" who have ruined so much of our lives with their determination to take all the risk out of life.
