Muzzin was my favorite character.
I know some claim he actually tried to murder David. I think it was just a cheap shot. David should have known better than to try to upstage a veteran anyway, or he should not have let Muzzin catch up to him again.
Still, I like Muzzin's competitiveness. I liked the way he taunted the Russian. Apparently Russia is a force in bicycling and even Russian cyclists wear beards. I liked the way he strategized. He knew all the "oldest tricks in the book", whatever they were. He was willing to let a rookie ride in his draft to 2nd place. I also thought it was really cool how he walked up to David and said, "Next year!".
From a pure sports perspective, I find Muzzin to be more inspirational than David.
