If this is truly available, I think you've got to do it. Hirsch is a great prospect and I'm all over the place saying you shouldn't trade him. However, Lee is an rbi machine. It would do a number of things for the team. It gets Lane out of the lineup. It gets Lamb off the field. It gets Berkman back to 1B where he belongs and needs to be to stay healthy. It allows Ensberg to move down to 5th, where I believe he is more suited.

I'd hate to lose Hirsch. Especially to a division rival that is only improving. Lee is a free agent to be and it could end up as a rental deal. However, if you want to win now, you have to pull the trigger.
