"Remember, you just need solid arms to get to the really good guys." I don't think that's at all true. In fact, that's what they have THIS year. Instead, Every reliever in the pen will pitch meaningful, high leverage innings, and that includes guys you bring up from the minors. It's just the nature of baseball. You are not going to be able to only use 2 or 3 guys in close games, and the other guys when it doesn't matter. If you want a good bullpen, it CANNOT be only a couple guys deep.
