Again, I REALLY hope I'm wrong this time (I am not wrong tho..) you don't need to watch those sparring sessions as they are not representative, both fighters have evolved A LOT since then. The issue is, Gane fights like a featherweight with HW power, with even better reactions, speed and timings. You have to be insane to think he doesn't have power because that's the thing.. he fights like a goat featherweight but with HW power. I just don't see him getting seriously hit even vs Francis.
p.s. could be compared to fury / wilder situation but imo it's even worse..
