Dunn done in AZ?

It doesn't sound like the Diamondbacks will be bringing back Adam Dunn. If that's the case, I heard Chicago sports radio talking about the Cubs potential interest in the slugging right fielder. The Cubs need balance in their order, and they might be able to afford him for year. Why wouldn't Dunn sign up and force Kosuke Fukudome into a platoon in center with Reed Johnson? It might work.
