yeah, but i don't recall ever disliking jericho or thinking he was doing a crappy job. at his worst he was better than the miz on his best day. miz was pretty good as a heel, while he's been horseshit as a good guy.
I bet we could make a thread with 1002 reasons why Jericho will always be better than Miz. So many others have done exactly this; I'd say it's actually routine for heels. Get really popular, get beat by Cena, get dropped to just beneath mid-card, get turned face.
