(Prob the wrong section, but...)
A few immediately spring to mind...
Mr Perfect - Sadly, we never really got to see how good he COULD have been thanks to the 80's WWE work-rate... Matches with Bret & Flair point towards what might have been.
Randy Savage (subject to fitness and sanity) - My favourite ever wrestler... Ooooh yeah! : P
Bam Bam Bigelow - Agile, charismatic, bad-ass bigman.. Bam Bam > Vader IMO.... Generally, severely under-appreciated.
Rick Rude... Again, injurys took away what probably would have been his best years and, also similar to Perfect, could work like a motherfucker!
Ricky Steamboat... WM25/Backlash09 says it all... "You still have it!" - WORD!
