A Clean Brutal Hit in Football Drawls Not Just a Flag [FBHW]

Nebraska's Kenny Bell blocking for a teammate knocks a Wisconsin play for a loop.

Ok it might not be the most Brutal hit ever but still the kind of hit football doesn't need right now. Kenny Bell just did what he was taught from the first time he put on pads. Blocking is a big part of the game and if you are unaware of whats going on then you will get hurt. At some point in Football (and many other sports)the players will get hurt and some injuries can last forever. So is Football a sport that needs to be changed to survive, or do the players know what they are getting to and have to accept that to play the sport?
