Probably because you realize that life is so much bigger than sports, and even OU sports. You probably feel sorry for him because you watch tv daily, and you read the paper, and you see the tragic end to so many lives of young men who have alot of the same character issues as TMG. If you are like me, you realize that a guy from his background can go so far astray quickly, that he may not be able to come back. That alone makes a human being feel sorry for another, just realizing how messed up his mentality must be at this point in his life...
Of course I did alot of ASSuming for your thought pattern, but I know you to be a pretty level headed person from what I see you post, so I made some educated ASSumptions.
