There are upwards of 40 to 50 arms in MLB who can deliver most of the raw stats Kimbrel brings but heretofore they have not been given the shot to fit into the role of "designated closer".
Most are aged well under 30 and cost between league minimum and maybe a couple million per year max.
The game's strongest analytical teams work for TB, NYY, HOU, BOS, CHC, LAD and PHI. And they are all moving away from designated closers, save for NY and - until Jansen's contract ends - LA.
The day of the "50 Save" man is gone forever. The day of the 40save man is drawing near. And for most teams, even a 30 save guy will be unusual.
Winning teams will continue to log 50+ Saves overall, but those will be distributed between two, three and frequently even four to five men each closing games based on matchups from the 7th inning on.
Joe Maddon, Terry Francona, AJ Hinch, Kevin Cash and Gabe Kapler are who you want to watch to better learn how pitching staffs will best be handled in coming seasons. And outside of NYY with their virtually unlimited payroll, no team will be paying a man who pitches under 90 innings more than $10m.....even that will be rare. Relief pitchers in general will be progressively dialed down salary-wise into the tiers of $3-5million tops.
