If that's not a hook then I guess everybody else is wrong.
Del Rosario comes forward swinging an uppercut. Barry stuns del Rosario with a huge overland left, smells blood and blitzes. A right hook lands on the temple and another right on the jaw puts del Rosario down for the count, slumped against the fence.
(Listen to Joe Rogan describing it as a hook as well.)
He wings a right hook from the orthodox stance to the temple and another right hook with his back foot leaping forward for extra torque to finish.
Any more debates.
