I've always hated the concept of designated pitchers for designated innings. During the World Series, when it was an all hands on deck type of qpproach, it seemed as though the role of a designated closer became less important. We had Price, Sale, Porcello, Eovaldi, and E-Rod ready to get the job done. Not bad. During the regular season, obviously things get approached differently. One thing I have always been in favor of is having the best pitchers top to bottom that you can find. I think that when you talk relief pitchers in general, Kimbrel is just about as good as it gets. His quality will not be easy to replace. It is easy to find relief pitchers but certainly not of his high quality talent.
