I'm like most of you in the WWE Universe: We're tired of these lame RAW guest hosts. Most of them don't know anything about the wrestling business and some of them aren't even big celebrities. If you're going to bring on someone famous, make it someone we actually want to see.
I mean, does anybody want to see Justin Long? The only reason he's known to most people is because he dated Drew Barrymore. Mostly these guest hosts are seen backstage with the Bella's and do nothing but plug their upcoming movie, TV show, or album.
But there are some certain people you could get to guest host and we might actually say "hmmm, I'd like to see him/her and see what they have to say or do". For this to work however, Vince would have to actually give them something to do other than be comic relief.
Most of these are my personal picks, but I think most of them can have a logical reason to be on RAW other than promoting their stuff. So here are my picks for potential RAW guest hosts.
