I believe they should leave the Smack Down Roster sit right now. Just keep building Cena, Benoit & Guerrero up. Hell push Holly and see what he can do, people are all assuming that his feud with Brock will be a catastrophe. You know as soon as the feud is done and if the fans aren't impressed, that he'll be thrown down to Velocity. But now the WWE should take some chances with Smack Down because who knows, maybe Holly can find his niche and become a likeable mid carder.
Smack Down Roster in 2004 Looks Good!
Brock Lesnar
Kurt Angle
Undertaker
Big Show
John Cena
Chris Benoit
Edge
Eddie Guerrero
