Dempsey had a lot of sparring partners. You can do a search for Jack Dempsey sparring partners. The photos you'll find show men of all shapes and sizes and races. Practically none of them have a similar size, build and facial characteristics of the guy jumping rope in that video? But the guy jumping rope does look like Greb. Which Dempsey sparring partner looks more like the guy jumping rope ... than Harry Greb does in that side by side comparison?
The face structure, head shape, and hair type, styling, and hairline all seem different from all other photos and the lone video of Greb. Also that skipping looked awful.
Greb looks terrible in all his training footage, particularly throwing punches. Looking bad in training just makes it more believable.
I lean that it is him. Has his shoulders, and while actually training and not fake training for cameras I think his hair would look different.
I don't see much similarity except for two eyes, two ears, a nose, and a mouth, but I have all of those as well and I'm not Harry Greb.
