I also remember players (Rivera, K-Rod, etc.) who started out as setup men, then became dominant closers when the former closers they were stuck behind (Wetteland, Percival) left. The fact is that some dominant setup men can continue that dominance as closers, others can't. There's no way of knowing which Marmol would be without giving him a chance. Having said that, I'm one of the proponants of using your best reliever as a stopper (in the most critical situation regardless of inning) rather than closer. I'd eliminate both the save and hold statistics as they currently exist and replace them with one statistic for relievers wh do their jobs, regardless of whether they finish the game, and allowing such statistic to be awarded to more than one pitcher in a game if they all do their jobs.
