John Cena....
No I am kidding.
But it's hard to just determine who's the "best" of all time especially since in wrestling, there are so many things to based it off. Sure guys like Bret Hart was a great mat wrestler who put a lot of effort into making his matches "believeable" but a guy like Hulk Hogan was more entertaining, truth be told, Hogan was able to get a bigger reaction back in his heyday by simply putting his hand next to his ear than a guy like Hart wrestling a good match. The Rock is probably the all time best example of a guy who was able to do both very well.
A tiny bit of topic here, but if we were disscussing greatest wrestling managers of all time, could anyone else besides Bobby the Breain Heenan be considered better?
We all have our favorites but for me, I was a huge fan of Hogan as a kid and despite the sad fact that he comes off as a total douche to me these days, he'll always still be a huge part of my childhood. Also I am a huge fan of Undertaker, Randy Savage, Bret Hart, Owen Hart, Ricky Steamboat, Jake Roberts, Steve Austin and (pruley for the fact that he was entertaining, even if he wasn't so great in the ring) Ultimate Warrior.
But if I had to choose out of that list, I would probably have to lend towards the Macho Man Randy Savage.
