Ric Flair great? Yes.
Ric Flair the best ever? I will say no.
Hulk Hogan better than Ric Flair? Not on any drug you offer me.
Listen, there is a reason why what the New England Patriots have done in the last 7 years or so is much more imressive than the Packers of he 60's, Steelers of the 70's, 49er's of the 80's, or even the Cowboys of the 90's. There is more parity and more competition in the NFL today, yet the Pats keep showing up, winning 3 out of 4 Superbowls. Wow.
Greatness is predicated as much on an individual's surroundings as it is on that individual. Flair is ONE of the greatest ever much the way the Pack, Steelers, Niner's and Boys were. But for sometime, Flair was one of the only choices. He was infinately more talented than Dusty Rhodes (and a hell of a lot better conditioned) yes Rhodes has to be elevated because there was a need. Who else was there before Sting showed up?
Also, some great wrestlers of all time simply lacked a certain peice to the puzzle - Hogan lacked in-ring ability, Chris Benoit lacked charisma for example.
The greatest of all time may be Bret Hart. Bret had the longevity, winning titles in the 80's, 90's and 00's with a mix of technical ability, charisma (to an extent), and amazing ring psychology. He went through some of the best periods of talent between Flair, Nash, Austin, Yokozuna, Michaels, etc.
The greatest of all time probably IS Kurt Angle. He is the total package. In ring prowess, charisma as a face or a heel, strength, pyschology, resilliance, the list goes on. He also has survived: The Rock, Steve Austin, Chris Jericho, Chris Benoit, Triple H, The Big Show, John Cena, Eddie Guerrero, JBL, Undertaker, Kane, Brock Lesnar, Edge, Hulk Hogan...need I go on? Angle has earned more success facing the greatest amount of challengers than anyone, and has more credibility because he earned a Gold Medal at the hardest contest there is - Freesyle Wrestling.
