For one, I'd have to say Alex Shelley. Shelley has definitely paid his dues in TNA, is one of the most over guys on the TNA roster, is fun to watch in the ring, has some real ability to cut promos and is at a time in his career in which something meaningful needs to be done with him. I honestly don't know why TNA has decided to virtually sit on Shelley's career since Sabin is out injured. I know people love the MCMGs, I'm a fan as well, but I think it's time to move on. They've done as much as they possibly can as a team in TNA and, let's face it, the tag team picture isn't exactly the peak of greatness these days. Unfortunately, I think Shelley is going to be relegated to the X Division or the tag team picture for life in TNA.
As for who else I'd pick, I think I'm going with Robert Roode. It's true that Roode hasn't done very much as a singles wrestler, neither has Shelley apart from a single run with the X Division Championship, but Roode is someone that's got that combination of someone that's still reasonably young, for all intents and purposes, and has the air of a veteran about him. He's got the goods inside the ring and on the mic, he's also just plain over with the fans and, also like Shelley, he's simply done as much as he can in the tag team scene. Beer Money is arguably the best tag team wrestling has seen in the second half of the 2000s but they've done it all in TNA. Their current run has been far from stellar and it just seems redundant to keep him as a tag team guy.
I know a lot of people are into Austin Aries and I like the guy too but it's far too soon in my view. He's been impressive thus far but it's only been a couple of weeks. I haven't been exposed to the guy until he came to TNA and I like what I've seen and heard thus far, but this guy might turn out to be a flash in the pan whereas Shelley & Roode have shown they've had the stuff in TNA for years. At the same time, however, Aries is only a few years younger than Roode and has accomplished a lot on the indy circuit. It wouldn't exactly get my goat if Aries got pushed hard and quick over Roode and my preference of Roode might be due to my greater familiarity with him.
