So at TLC 2013, we will finally see the match we've waited a lifetime to see, when John Cena clashes with Randy Orton to unify the WWE and World titles, once and for all. Honest, this time. The concept of unifying multiple titles is one that every wrestling fan seems to understand, but it's actually a fairly recent development. The earliest example that most people would know about is Nikita Koloff beating Wahoo McDaniel to unify the US and National titles in 1986, and then beating Terry Taylor a year later to unify the NWA and UWF TV titles at Starrcade 87. The Russians always were fans of streamlined labor, I guess. Granted, WWE and other promotions have attempted to sell us this particular bill of goods before, and with only varying degrees of success. We're going to play by rules here and only talk about matches specifically advertised as unification matches, so ones where one guy walks out with both belts and is forced to vacate one of them (Hogan v. Warrior being the best example) do not count. Matches for unofficial titles (like Taz's "FTW" title) also do not count. Onto the countdown!
