I know it was at least one. Perhaps, that had something to do with what looked like Kolat's conditioning issue, I.e moving a bigger guy around took it out of him. But, Kolat often looked like this in his few loses. An archetypal pinner, Kolat would sprint from the gun to put the guy down or at least run up the score. If he couldn't, he would fade quickly. Again, this was rare bc he usually got it over with quick.
After reading that (SI?) article (you know the one relating the cattle prod story?), I always wondered if there were environmental causes for the apparent conditioning issues (e.g. the chain-smoking dad).
