For me, it all depends on how much longer the Nexus is going to be alive. After the Cena vs. Barret feud, it was thought that Nexus would have ended. However, as of the last week of 2010, we were shown that Punk took the new role as leader for these guys. The Nexus is built to be a dominant group; and with Punk, the Nexus is able to keep some relevance.
Keeping this in mind, I would be more than happy to see Skip back in Nexus. Skip was the one that, in a sense, supplied the muscle to the group. But ever since Skip left, this attribute that the Nexus had was gone. Having Skip back would without a doubt regain the great attribute Nexus once had.
Though, with that said, I doubt that this is what's going to happen. I believe that when Skip comes back, he will most likely go to the mid-card scene in Smackdown and build himself there as a dominant force. Can't say this is what I'd prefer, but it'swhat I think will most likely happen.
I'm very against Skip joining a force with Michael Tarver because, well, there will be nothing for them to do. Sure, they'll hunt for the gold (etc) - but what then? Chances are, they will split up; go their seperate ways; and all their work would be for nothing. The WWE doesn't really care much about their tag division anymore and I doubt that they will anytime soon. So, really, having Skip in a team with Tarver is more than pointless.
Whatever the case, I hope to see Skip back soon. He was always one of my favorites adn I was very saddeed he left in the first place. Here's to hoping the best of luck for good ol' Skip.
