You're going to pay a guy 10 million to ride the bench and DH for 20 games a year?
I have a hard time believing the Lerners would be ok with that.
Forget the Lerners, LaRoche is way too good a bat to be a pinch-hitter and occasional DH. It's not like this team is overflowing with quality hitters, so you want a guy like him batting as much as possible.
