First off, I played football from middle school into college, and stopped playing after I was deployed. The amount of crap that is said back and forth in practice and in game is close to abuse, but on the other side that's the goal, get in the sobs head. It works, can you imagine what the media would do if every linemen was recorded? It would be rated nc17. I can't even count the number of times in the Military and on the field that I heard the n-word used. Personally I think at the end of all this Martin will take the hardest fall. Even my middle school coach said thing that hurt me but did I play better, I sure did. It's a sad story, but it's a story that the media knows nothing about, and that's the problem.
This is certainly a plausible explanation for what happened. As Ricky said "The NFL is like a closed fraternity, it's really not made for everyone." We will find out more in the coming weeks I'm sure.
