The correct answer is HBK No idea why Triple H is getting any votes or why he's even on the poll, he's a cancer who single handedly destroyed Raw for, what, 2 years? I find it hilarious how everybody complains about how Cena is so predictable and boring, yet praise Triple H. Triple H is half the wrestler Cena is (remember, in the last 5 years, we're talking post-first-quad-injury Triple H, the lazy fuck who was married to the boss's daughter and thus had a push for life regardless of his performance and showed it in every match that didn't involve his buddy HBK), doesn't have a quarter of the charisma, and his matches were 10x more predictable.
Anyway, HBK's the MVP. He's always uber entertaining, both in the ring (for the love of christ, he married Vince fucking McMahon to a match of the year! I repeat, Vince McMahon in the match of the year!!) and out of it. Plus he's always willing to job to get somebody over...Triple H, Orton, Benoit, Edge, Kurt Angle at WrestleMania, Hulk Hogan, then had the aforementioned match of the year with Vince McMahon (did I mention that HBK carried Vince fucking McMahon to a match of the year? that may be the single most impressive feat in the history of wrestling), John Cena at WrestleMania, and most recently Randy Orton again.
I do have to acknowledge Edge, as he has certainly been the heel MVP of this time period, and he would give HBK a run for the MVP of the last 3 and half years. Unfortunately, you have to remember that in 2003 he broke his neck and missed over a year of action, and it doesn't help that he suffered a torn pec during his first legitimate world title reign. That was his first chance to really carry the company (well, the brand) and it got cut short.
