At 6-foot-4, 272 pounds with world-class athleticism, Cleveland Browns defensive end Myles Garrett is a quarterback’s nightmare.

Veteran Browns quarterback Case Keenum can sleep a little easier nowadays knowing the All-Pro pass-rusher is on his side.

Garrett has been posting videos of his offseason workouts, which — are in short — pretty insane.

“I’m in a different mode,” Garett wrote in the caption of his most recent post.

Keenum retweeted the video, writing: “If this dude wasn’t on my team I would be having some serious issues falling asleep at night after watching this.”
