Morrison would have the most to gain really ..........

# Cena to heel --Lose merchandising from kids and there parents.
# Orton to heel--Too soon and he just turned face .
# Edge to face--Again too soon he just turned from face to hell
# Sheamus to face--Who would care really ?
# Jericho to face--- And do what?His best feuds and matches come from him as the heel .
# Morrison to heel--Most to gain
# Mysterio to heel--Read Cena
# Miz to face--- Hes on a roll as heel leave him be
# Punk to face--- Potentially but where would the storyline go he has built up with Straight edge , Im better than you usually works best as heel maybe after it ran its course.
# Kingston heel--- I personally dont care if he's heel or not I dont know his current storyline on Smackdown I dont watch , however when he was on Raw he bored me to death the gimmick is a 80's mentality of a stereotype aka "Dashing "regardless if they work or not they don't for me let them be more of themselves and watch ..
Rock Austin were given the ball that way.
