its funny that you mention taker cause when taker is on SD he is the main event.
triple hhh putting over del rio? how about no. del rio sucks, he is mid card at best (if that).
-christain could do good but he isnt ready to be the big kahuna of a brand yet. but as long as he keeps showing up he will get their.
-chris masters, funny how you forget about him, infact, most people have, but lets face it, he could be big if the wwe were to use him.
-triple hhh on smackdown is unlikely cause he only works dark matchs now, and is only around if the deadman is around. so with this lack of wrestling i dont expect him to move to smackdown ever.
-heath slater and justin gabriel, maybe not the people carrying SD, but if they left the corre these 2 guys could be huge.
-mason ryan, come draft time have him drafted to SD, he could be a dominant force.
-skip sheffield, if he should ever return have him go over to SD, within a year of 2 of him dominating people and people getting behind him he could be huge.
at the moment most of these guys arent to big, but they can be blown up to be big names, of course, wwe would have to give them a push and skip would have to return.
