I say lesnar, cena because he's strong, show because he's huge, and adr.
none of them would be my first picks though. other than that my votes go all to people not on this list
yoshi tatsu, booker t, jericho.
tatsu because he apparently smacked Sheamus up a bit when Sheamus was swinging his dong at him and and DiBiase and getting physical when they were arguing about Sheamus not cleaning up after himself back when they were rooming. booker because apparently he is dangerous. and jericho because of the whole Goldberg.
