I guess not. When I took wrestling it was 90% ground and maybe 10% takedowns.
I have to admit wrestling isn't something I was ever that interested in. I only took it more than usual because otherwise I'd have to play badminton. Our classes were taught by the team wrestling coach, and our team was one of the top teams in CA for whatever that is worth, but I wasn't on the team.
Whatever submission wrestling they were doing at that school, AMC, looked like bad judo groundfighting so I didn't bother with it. But Pankration is probably something different -- I have no idea.
When I took judo it was around 70% throws, 30% ground fighting.
All I can say is that Judo seemed to do a lot more standup than any place that claimed to do wrestling I've ever been. Even BJJ is supposed to be a lot more ground fighting, like 90% or something.
