Colorado athletic trainer gets leveled by Jabrill Peppers on sideline

One of the first things your coaches tell you when you begin playing football is to "keep your head on a swivel."

This is shorthand for "Be aware, because there are 11 people out here trying to kill you at all times."

This is why I’m sad for Colorado’s athletic trainer, who became collateral damage on Saturday after a hard-charging Jabrill Peppers couldn’t stop himself in time after running out of bounds on the Buffaloes’ sideline.

See that?

He did everything he could. He swiveled his head. Didn’t matter. Peppers comes for all of us. You can only hope your collarbone can withstand his misplaced momentum.

Dan is on Twitter. His motto is "Keep your butt on a swivel chair in an office and far away from fast-moving giants."
