I've only seen one exotic drop in crucible and it was Suros Regime and the player was last on the team. My friend was given NLB after coming in first on a winning team. He texted me the picture. It's quite humorous. A horrible player was awarded with (at the time) one of the best exotics in the game while a traditionally solid player was rewarded(?) with one of the worst exotics in the game.
