If you watch the behind the scenes stuff when Dana took the UFC guys over to Pride, it was obvious Chuck was there for Dana. Theres no question. Chuck was there to win, but he was pretty much there for his friend. I think at the end of the day, the motivation is plain to see. You punch to Chucks jaw and he drops and if I saw my 40 year old buddy take its like that, it would be hard.
When Rashad knocked Chuck out, Im pretty sure then and there Dana decided it was time for Chuck to let it go. Chuck was out for a long time and anybody fimiliar with boxing knows those hard punches take their toll and eventually the fighter doesnt get up. Theres to much risk and I'd like to think Dana wants his friend to start living the good life. If anybody deserves it, its Chuck.
