and Hogan, Macho Man, Triple H, Austin & Roman - I'm dubious about this take.

You are underestimating the strength of bamboo:

Was JeriKO last season, or we including it? Cuz that was great too.
(Truth/Goldust, not so much for me.)

Not necessarily, he's probably just selling. Trained once with a kid who was great at that too, but little else.
Some pale enough guys can just hold their breath and tense and go beetroot red. My guess is Lesnar is near the top of that list. Looks like his head is about to pop!
