His ERA+ the last 4 years: 111, 117, 106, 105
that makes him a good #2 the first 2 years and a OK #3 the 2nd two - he's no ace, and has never been an ace - not by his percentages or results. He does throw innings, which is valuable, but doesn't make him an ace on its own.
He is now the "premium" SP on the market with multiple teams seeking his services.
He will get more than 4/60, 5/85 seems closer to the mark.
He'll be 29 before the season starts.
So as I said. He's cashing in because of a weak market AND he's hardly elite like his price tag. True when I wrote it, and true now.
