IMO, I don't think that's an overpay. $15 million a year for a starting pitcher is almost cheap now. Feldman got $10 million, Nolasco got $12 million, Colon got $10 million a year for 2 years at 41 years old. And then Johnson got $8 million and we are paying Blanton $7.5 million. It's a gamble, but for $3-5 million more than what these starting pitchers are making per year, there is a lot more upside to the gamble.
Now if we are talking 6/$147 like what Greinke got, then that's an overpay.
