You're the first person to bring up WAR in this thread. But in doing so, you kinda made my point for me. Chapman is a 3 WAR player. That's pretty good. Over the past 3 1/2 years, Denard Span has averaged a little over 3.5 WAR per season. He was traded straight up for Alex Meyer, yet you just claimed it would take much more than Meyer and Arcia - two top 100 prospects - to pry Chapman away from the Reds. Reliever values are inflated for what they bring the team. Yes, they pitch important innings but no matter how important the innings, they still only pitch 1 in 20 team innings. Unlike a position player, they are one-sided. They pitch defense for an inning. They have no offensive value. Under those restrictions, there is a limited influence one can have on the game. It doesn't matter how good you are as a pitcher, if you only pitch 1 in 20 innings and don't swing a bat, your overall influence on the game isn't going to compare to a good position player. That seems kinda like common sense to me, not advanced analytics. The Nationals got three years of cost-controlled Denard Span for Alex Meyer. If the Twins can't get 1.5 years of non cost-controlled Aroldis Chapman for considerably less than 2011 Alex Meyer, the Reds should be laughed out of the room.
