in no particular order
christ benoit - lacked mike skills but was so talented in the ring and could carry anybody (except for maybe the great khali).
shawn michaels - great on the mike and in the ring. thanks to his size he can pretty much do as well as he did when he was younger.
the rock - perhaps the best ever. could work a mike like no other and a was damn good in the ring. too bad he's not coming back for anything more than a hogan-like schedule.
kurt angle - pretty good on the mike. and his in ring skill is one of the best.
rey mysterio - so fast and agile, with moves few could do (amazing red is one of very few). such a face and an easy fan favorite.
eddie guerrero - so good with a mike and so good in the ring. i miss ya eddie.
bret hart - decent mike skills. and one of the best ever in the ring.
hulk hogan - biggest name ever. so charismatic. good in the ring when he was young. now not so much.
the undertaker - a presence few can match and for his size, wow.
chris jericho - excellent on the mike and in the ring. i can't wait for his return.
more?!?
teddy hart - seriously, this guy defies gravity. he's amazing. decent on the mike.
cm punk - a true legend in the indy scene. such charisma and talent. about time they decided to give him a push in the wwe.
