As strange as it may sound, I think Gable is underrated as a wrestler. I was checking a bunch of lists of the all time greats, and while he is always high up, is typically lower (sometimes much) than I would put him. I put him right at the top in all areas (high school, college, international). Cael might be a tad higher for college since Gable lost one match (if you think that is the differentiator), but Gable dominated similarly (maybe even more) and of course couldn't wrestle as a freshman. Almost equal, and you can't get better than Gable in those other areas unless you are talking about longevity.
He was undefeated in high school and smoked everyone internationally for the short time he wrestled after college (then got coaching so retired). I can't think of a better overall wrestler and hard to be higher rated over a lifetime if you really look at what he accomplished from high school on. We do tend to remember what is more recent. Wilt is still the greatest!
I especially like winning the Olympic gold in 72 without giving up a point.
