This is the first we've seen of this video, though it was apparently made last season sometime (we're guessing the October 9 Jaguars win over the Bengals).
It's Jaguars defensive tackle John Henderson calling on a trainer, or intern, or whomever, to get him appropriately excited and pumped up before the game. By, frankly, slapping him in the goddamned face.
"Come on, Joe! That ain't hard enough! Come on, Joe." The poor trainer seems awfully bewildered by this unsuspected part of his job description. Uh, he's not gonna kill me for this later, is he?

(Easy joke alert: This is actually how Johnny Weir prepares for his competitions as well.)
