What a tough issue for fans and athletes alike. Football is a barbaric sport and let's face it, that's why we like it. The more that they remove the barbarism from the sport, the less I like it. Tackling a QB in the pocket may as well be 2 hand touch the way they've changed the rules, WRs have little fear of going across the middle, a RB can lower his head and shoulder pads and not worry about a helmet to helmet collision. There's a really fine line here and I'm not sure where it is. Why don't we have two full units of offense and defense and the whole unit comes off the field every play and every player gets checked before they go back in. A bit tongue in cheek there, but the question remains, how far is too far to change the game in the name of safety. We all want the players' safety to come first, but if we're really fanatic about it, why don't we just do away with football all together?
The biggest problem is the warrior mentality of the athletes, you're trying to change a culture that has glorified being tough and dealing with pain. The very thing that you're telling them to do goes against everything that has made them successful at football. How are you going to get someone to change that when it is what go them there in the first place?
