Let's think this one through.
If you've got one 96 mph short reliever, one guy who can come into a tight game with men on base and shut down a rally...
Is that what he's worth to you? The same +1 win as, say, Michael Saunders is worth?
............
Mark Lowe is a whale of a lot tougher to replace than all the +1 WAR position scrubs. He's a +2 player to me.
Hey, you deal Lowe and run into some blown leads, a team problem, in the 7th and the 8th, is that two games in the standings or five?
