Detroit Lions head coach Dan Campbell left quite the lasting first impression two years ago when he stated that his players would “bite a kneecap off” of opponents during his introductory press conference.

That soundbite continues to live on in NFL lore. Campbell quickly became one of the NFL’s most popular personalities following that simple press conference, but he is by no means a one-hit wonder with soundbites.

Per Jeff Risdon, Campbell had another epic quote when he explained how to they grade prospects at the NFL Combine.

“You grade off tape, not what happens with guys running around in pajamas,” Campbell said.
