I kind of get it and I kind of don't. Someone is getting knocked out either way. Why not prefer that someone to be a d-bag you don't particularly care for? Ideally all fights would be like Chuck vs Tito for me. A fighter I love beating down a fighter I hate.
Idk, I guess I don't have that kind of hostility towards any fighter in the UFC. It's good to see guys get KO's and move up the ladder, but always I feel bad for the guy who gets dropped.
