Amari Cooper is already one of the best pure receivers in the NFL, but he decided his game needed another element.

Cooper basically already has it all — athleticism, speed, quickness, work ethic, ability and route running, but he decided he needed to add some muscle. And by “some” muscle, I mean a lot of muscle.

After back-to-back 1,000-yard receiving seasons and two Pro Bowl selections, Cooper is ready to tell every defensive back to get off of his lawn, literally.

Remember when Pacman Jones abused Cooper as a rookie by slamming his head into his helmet? Cooper might make someone think otherwise with his new physique.
