...granted, this is based on my biases and age, but here goes....
1) Bob Backlund - ultimate baby face and technician.
2) Shawn Michaels - made all his opponents look good.
3) Ric Flair - best promo guy and could easily go 60 min.
4) Bret Hart - excellent technician, best there is...
5) Jimmy Snuka - probably inspired more people to become wrestlers (Tommy Dreamer, Cactus Jack) than any other wrestler. Responsible for the high flyers of today.
6) Kurt Angle - Puts on a great match
7) The Undertaker - Undefeated at Wrestlemania (or at least was...)
8) Chris Daniels/Curry Man -- Best of the current crop of today's wrestlers.
9) Steve Austin - Cuz Faizal Enu said so.
10) Rick Steamboat - Had the best all time match with Randy "Macho Man" Savage
11) Edge - TLC
12) Greg Valentine - Great heel
13) Iron Sheik - Better Heel
14) Mick Foley/Cactus Jack - Did more for extreme wrestling than any body...
15) Terry Funk - except Terry Funk
16) Kane - Been at the game a long time. Great at playing the monster heel.
17) Scott Hall/Razor Ramon - Ladder match with Shawn Michaels a legend. Could have been better.
18) Ivan Koloff - Underrated heel from the 70's and 80's
19) Rick Martel - Great technician and personality...
20) Sargeant Slaughter - Really great at working stiff.
