My favorite was Kenny. He was a decent guy, and a fighter. And especially liked his no quit attitude. No matter how bad things got, you could tell that giving up was not in him. He could give Mohammed Ali a run for his money! Not in a brawl of course, but definitely in spirit.
I do have to admit, I also liked Chuck as well. Even though Kenny could be a badass in certain respects, Chuck was definitely not afraid to stand up to him. Even though Chuck was I'm going to guess to be around 15 years Kenny's senior if not more, and therefore probably no match for Kenny in a brawl, Chuck's character possessed manly courage.
I think it's a shame the writers saw fit for him to last for only one episode. It would have been interesting to see how his character reacted to the events that went down toward the end of the game.
