How Can I Miss You When You Won’t Go Away?

Ever hear that song?  It’s pretty funny and it really reminds me of the situation with Johnny Damon.  Stories like this one and several others keep talking about how Damon wants to come back to the Yankees. 

The thing I don’t get is why Damon kept playing games with the Yankees in that case?  Why did he let Boras do the negotiating if he wanted to come back?
