Wow now this is totally unexpected. So Craig is guaranteed between $42MM-$45.5MM for 4 years, or $10.5MM-$11.375MM per year on average, and if the option for $13MM is exercised in 2018, then it could go as high as $58.5MM or $11MM-$11.7MM/year on average.
I'd have to say this contract for Kimbrel, who is as an elite closer as you'll ever get, is well worth this money. While this is a lot of money, $11MM-$11.7MM/year for 5 years, Craig is well worth that. This was the only way we were going to keep him in Atlanta past the next couple years. I think this deal may be the most important, and best extension we've done this offseason. I'd give this deal a solid A.
