Someone who only performs when a superior observes them; not a team player. From US Army Ranger school slang for a ranger student who doesn't give his all unless he is the one being evaluated on a mission - ie they only perform in the spotlight.
Jones is such a spotlight ranger. He didn't help with the project and then when the boss arrived he handed out the packets as if he did all the work.
