Canelo doesn't punch nearly as hard as Lemiuex or Jacobs. I see a much more aggressive GGG than against those guys.
It was due to body shots. They take the air out of you and make you less active over time. Don't take credit away from Jacobs.Plus I think they played very cautious during the Jacobs fight not just because of his power but also knowing the risk of losing the fight would also lose them any shot at a Canelo match.
