Or...Nick Diaz hits like a truck.I think the Diaz punch just surprised him. He didn't see it coming and was moving right into it. It's pretty clear it was not a hard thrown punch and Diaz has not displayed KO power in any other fight pretty much. It was just the timing, the momentum of Lawler moving forward, Lawler not bracing for it, and the placement of the strike.
Sneaky ass uppercut! The follow up was deadly
Diaz' punch wasn't even that hard, slept him with a hook.
