Of course every team could always use another premier arm in the pen. I have to admit, though, I feel kind of bad for Rondon. He allows the 2nd fewest baserunners in baseball, ahead of Miller, Chapman, Betances, etc and even after getting Montgomery the talk is still about adding a big arm in the pen. I get it, I do. I want a pen full of closers and "firemen". I just think Rondon flies under the radar, even in Chicago.
