Re: How much does WK make?
That's what happens when you have positions where you can't prove that success is YOUR "fault". Whereas with a player you can demonstrably show the impact and thus justify great salary differences (20 million vs. 300,000). However, for other positions, all you need to do is outbid the other guys and there's so much unknown and/or unmeasurable about the quality of the person being hired that you can't justify great variation from the other bidders.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
