I don't think Triple H moving to Smackdown is gonna cause a huge dent or chunk from Raw as a show. I mean, i like HHH, but he's not God or anything, he's just switched. Raw received a HUGE advantage from the past draft. If anything Raw has, once again, gained.
Triple H fans will just have to watch him on a different day, but i doubt they're gonna shun Raw because it's Gameless.
This'll give Raw an opportunity to change things up a bit, and it sure as hell has shown. I mean the show's champ goes from HHH to CM Punk, who'da thunk it??
Hopefully this won't mean Smackdown will revolve around HHH now, but this could also be more great opportunities, HHH willing, for some of the fresher faces to be put over, and who better than to get one over the Game for a nice push?? But, like i said, IF HHH's willing (and lookin at his recent Wrestlemania streak, excluding 24, i'd say so).
Taker vs HHH would make for some great matches and feuds, but i'd hate to see yet ANOTHER face vs face, which means this could be a good point to turn HHH back to the Cerebral Assassin, aka a heel.
Time will tell.
