Defense is a priority for the Mariners, I strongly believe that. There are higher priorities, but defense i son the list. They're bats will certainly make up for their defensive woes, but I wouldn't want more than one of them on my team, and certainly no more than two. They also tend to come with big contracts, and careers that fall off before the contract ends.
It sure wouldn't hurt to have one on the team, but Zduriencik hasn't pushed to get one. I believe one would help this team out immensely despite the drawbacks. The value of just one of them would far exceed the expense in my opinion. I'm certain that most fans also believe the same thing, but the fans don't pay his salary, the FO does.
My newest 2013 AAP's:
Carson Smith, Generals bullpen pitcher
Carlos Peguero, Rainiers outfielder
Rich Poythress, Rainiers first baseman
