Yeah, look at the team Adrian Gonzalez has around him. No excuses there.
And what about Dukes? Why is he able to thrive hitting fifth in our line-up while Z can't even hit that well hitting third?
Some guys are studs and can hit in any lineup you put them in. Others are the by product of those around him. Who knows, maybe one day Zimmerman will become the type of player that can hit in any lineup or even the type of player that can make others better.
