Adam Dunn is figured to make a hefty salary if/when he lands his LTC. What I gather is that the team signing Dunn and trading either Kearns or Pena for a pitcher is the most likely scenario. If that pitcher is worth anything, he will cost the Reds a lot more money than Kearns or Pena would. That means we have to pay for Dunn's LTC and a new pitcher's high dollar contract.
So what if we traded Dunn? The money used for his LTC could cover the pitcher we get in return for him. Or could come close. Then we still have the money we would have used on a new pitcher acquired after a Pena/Kearns deal. We could sign a FA pitcher in this sense for that would be money.
Rotation:
Dunn Trade
FA
Harang
Claussen
Milton
We would still have a great outfield and powerful bats and we get two top of the rotation type pitchers. The question becomes, is Dunn worth two SP that could anchor the rotation?
