Which 4 would you keep
Kimbrel is the closest thing to Rivera in his prime around. Zimmerman is a young guy with 1.5 above average seasons behind him. If you were drafting a keeper team in 1998, would you take Mo Rivera or Chan Ho Park? I rest my case.
Kershaw, moore, gio, zimmerman. closers are not normally worth keeping.
When your closer is racking up 16.7 K/9, he can be an exception
Kershaw, Gio, Kimbrel, Moore (In that order)
this is the correct order
kershaw,zimmermann,gio,and moore. i would'nt argue if you kept kimbrel.
