The 162m contract was a decision made at the ownership level by Peter Angelos. Buck Showalter and Adam Jones went right passed Duquette to lobby Angelos to sign Davis. Duquette and his staff may have handled the paper work but the decison was made above him.
The point is well taken that Davis is still being paid by the O's but is not on the 40 man roster.
I found it interesting that after a tear down and rebuild by Elias the team still has so many players acquired by Duquette 4 years after he left the team.
