I'm not talking about signing a lesser closer just to save money. IMO, a 'very good closer', aka a Craig Kimbrel type, can be found for a lot less money than what I think Kimbrel is going to command. The best closers seemingly often come out of nowhere. Also, those huge contracts to relievers almost never work out.
As good as Kimbrel was last year, he was about the 8th best closer in terms of save %. Some better closers are making $2 to $4 mil a year.
