How about this scenario:
The Reds are still negotiating with Dunn on a contract. He has stated that he prefers to play the OF. Maybe that's one of the hangups to signing him long term. The Reds bring in Hatteberg to play 1B, and tell Adam he will move back to the OF for the duration of his new contract. Hatteberg is signed to 1 year because he's the only 1B option worth a crap out there right now. That gives the Reds 1 year to find a long term replacement. Maybe the LA deal with Milton and WMP for Choi and Perez is actually being discussed with Choi being one option for Krivsky long term?
