Re: If these Reds were free agents...
Dunn would easily get at least 12 million per year.
Kearns would probably get the standard 3 million per year contract for one year that decent journeymen (like Reggie Sanders) get. He's just not that good, and has a poor track record. I can't see a bidding war for him.
Harang would probably get at least 9 million per year. Look at what Byrd and worse guys got last year.
Lopez is hard to peg down. A lot would depend on how strong he finishes this year. A strong finish could get him 10 million per year. A weak finish knocks him down to 5-6 million per year.
