"He's got to alter the perception that he can be a troublesome clubhouse presence, a reputation he earned in his years with the Royals," writes Buster Olney. "A lot of teammates there thought he was not invested in the rest of them. There are already some teams who won't consider Greinke because of the uneven nature of his exit from Kansas City."
