Yes, this is another post about the Red Sox bullpen, because it’s the only thing going on right now. I’m just about as sick of writing these introductions to Boston’s relief unit as you are of reading them, but that’s the way of the world. In case you somehow don’t know — in which case I kind of envy you — the one area of the Red Sox roster that is likely to be added to before the start of the season is their bullpen. After representing their biggest issue in the regular season before coming together (with the help of some rotation members) in the playoffs, they lost Joe Kelly and possibly Craig Kimbrel, leaving a couple of big holes.
