Emmanuel Sanders thought he had just witnessed Josh Norman lose his mind during a DraftKings focus group.

The Denver Broncos wide receiver, however, didn't realize Norman and everyone else was in on the orchestrated joke.

As the conductor asked the group questions about Norman, Sanders watched the Washington cornerback seethe at the negative responses. In Sanders' eyes, nobody on the panel realized they were insulting someone sitting in the room.

They even tested Norman's willingness to play along by praising bitter rival Odell Beckham Jr.

Sanders watched the defender curse out the participating group members as part of the prank. Perhaps this was Norman's indirect way of getting payback on Demaryius Thomas.
