I don't know if I could pick just one, though I have at least a list of viable contenders, in no particular order.
CM Punk - Punk has proven himself to be a consistent, strong draw for WWE since he was elevated into the spot of a legit main eventer. From an overall perspective, Punk is one of the top in the world right now. Like almost everyone who makes it to the top in WWE, Punk has his fair share of haters. But, as I said, he's someone that's shown he can draw for the biggest company in the world. He has the ability in the ring, he has the personality, the charisma, the promo skills and the passion. I'm not saying that Punk is a massive mega draw or anything but look at the facts as we know them. Punk was obviously producing and producing big time, otherwise Vince McMahon wouldn't have kept him as the longest reigning World Champion for more than a quarter century.
John Cena - What a lot of people tend to look over is that pro wrestling is a business. It's a business whose primary goal is to make money. Like him, hate him or indifferent; John Cena is the biggest draw in pro wrestling and has been for the better part of a decade. Some might not be all that wild about Cena's more family friendly kind of character, which is understandable. I like the guy and he even gets under my skin sometimes. But, you can't argue with the results. Cena can connect with fans like few people can. Whether he's getting booed or cheered, his reaction is second to none. It's when you don't get a reaction that you should worry about. Cena has shown time & again that he's very strong on the mic and can deliver passionate promos with the best of them. Cena's also entertaining, consistently entertaining, in the ring. He might not be a technical wiz like Kurt Angle or a flashy high flyer like Rey Mysterio, but anyone who says "you can't wrestle" to John Cena is a fool.
Bobby Roode - Roode has consistently been one of the reasons I've continued to watch TNA even when what they were putting out Grade A crap. Bobby Roode is someone that does have the "It Factor". He has a good look, he's got the skills in the ring, he's got the charisma, he has the promo ability. In a lot of ways, Roode puts me in mind of a smaller Triple H, though Roode uses a bit more technical stuff than Triple H. Roode has that sort of intensity that's akin to Triple H and is at his best when he's in a serious mind set.
Austin Aries - Austin Aries reminds me a lot of CM Punk, only more muscular. Like Punk, Aries is someone who is thought of as one of the overall best in the world right now and with good reason. Aries is one of the genuinely few guys to come through TNA since I've been watching that struck me as someone that could be a legit top level player. When Aries arrived, TNA stuck him in the X Division and, let's face it, the X Division's relevance has barely registered as a blip on the radar for about 5 years now. Even though Aries was put into matches with the same couple of wrestlers in one variation of a gimmick match after another, he still brought interest to the X Division. Aries was a star and, frankly, it looks as though he wasn't going to let something as mediocre as the X Division keep him from being a star. The X Division didn't make Austin Aries relevant, Austin Aries made the X Division relevant. Want proof? Just look at where the X Division is now compared to this time 1 year ago. It's back to being its same old generally irrelevant self since Aries isn't a part of it.
Daniel Bryan - Daniel Bryan is someone who proved a lot of people wrong in 2012. Bryan went from being a paint by the numbers generic babyface to one of the most over heels on the roster within the span of a few months. Bryan has the goods in the ring, that was obvious to anyone whose ever watched him wrestle. He can brawl, he can do the high flying stuff and he's a technical wiz on the mat. But what held Bryan back was his seeming lack of charisma & personality. After he cashed in his MITB contract and won the World Heavyweight Championship in December 2011, it shocked people. Already, people were expecting him to drop the title within a couple of days. Not only did Bryan not drop it, but he held onto the title for somewhere in the neighborhood of about 4 months and had a meaningful run with it. Bryan spent the first half of 2012 wrestling as a World Champion or wrestling to become a World Champion. In September, something even more surprising happened. WWE put him in a tag team with Kane and they were actually good. They were featured in some of the genuinely funniest moments I've seen on WWE television in very long time. As part of Team Hell No, Bryan helped make tag team wrestling mean something in WWE again. There's work to be done still with it in WWE but, frankly, Bryan has done his part. On top of all that, Bryan is a significant moneymaker for WWE. His segments on Raw usually draw really well and his merchandise is among WWE's top sellers.
There are probably more, but those five are wrestlers who have proven themselves to be someone who either is or potentially can be a franchise player for any company.
