I'm on the fence about calling WWE a "sport" but if it is considered a sport, then Chris Benoit would definitely get my vote. He has basically been written out and censored from anything in WWE records/archives, Future generations and fans of the respective sports will know who OJ, Mcguire, Bonds, Paterno, Woods are, in future generations, and even this kid-generation WWE, many won't know who Benoit is unless they seek outside sources aside from WWE. I don't think anything can compare to a double-murder suicide either, OJ maybe, but Benoit took his own son's life, that is really fucked up.
I voted Paterno before I read Benoit just cause Paterno was a legend at Penn State and to fall that hard and to be fired is really a hit to his reputation. That guy was king at that school, now there is so much outrage against him.
