ERA (even though IP isn't drastic) is a bit higher for a claser at 3.28
I can't see moving him above: Kolb (39 saves for a bad team), Shingo (19/20 saves once he got the job), or Hoffman. So that leaves guys like Percival (maybe), Dotel, and Izzy as the only possibilities.
I'd bring Mota up higher. They might not be giving him love because of the rough transition from be a set up go to THE guy recently. But I think he has the stuff and the mentality to do it. He did the job nicely the week that Benitez was out.
