First off, believe me when I say that I do not underestimate the value of having a strong pen.
That said, I have posted many times that the bullpen is not an area that I would spend a lot of money on. A good pen, with a good closer, can be assembled without spending the type of money and prospects that we spent on Kimbrel.
Yes, it makes us all feel good, myself included, when we see Kimbrel come in and dominate the opposing line up like he''s been doing all year. However, most closers are going to get the job done the great majority of the time. They might not do it in as dominating a fashion, but they get the job done. The difference in value between Kimbrel and most other closers is not worth what we paid for Kimbrel.
We overpaid twice for Kimbrel - once with prospects and once with money.
