HH could wrestle. But he didn't need to in the US. If you watch some of his matches in Japan, it's night and day. He was surprisingly good. Here is a short video from 1983.
And yes, I know it's pretend fighting. But it still needs a lot of skill to perform on the level of Bret Hart. Pretty ironic that his career was ended by a charismatic, meaty big guy who can't wrestle.
Ich habe ihn zuletzt öfter auf Lemmy gesehen als im TV.
