Dan Harren would cost 20 million in today's market
Do you think that will be the case after the CBA negotiations? Salaries have simply ballooned to insane levels and it basically means you either get top dollar, settle for $9 million a year (I know, easy to settle for), or you're getting somewhere between league minimum and 2$ million. The folks between that two and nine range would be your Kendrick, Eaton, Zimmerman types where you're hoping to squeeze one more season out of their rapidly dying careers. Good bullpen guys (non-closer) likely sit in that range too. Obviously, certain players have an incentive to drive the ceiling up, up, up and away. But not that many people are actually Bryce Harper, Anthony Rendon, or Machado.
One would hope the union tries to get the average salary bumped up and put a cap on handing out more and more ridiculous contracts. Of course, I have a generally skeptical view of many unions, and not sure they'd be acting in the best interests of all the players, or trying to work on getting the top dogs even more cash while depressing everyone else's salary.
