I said all offseason the reason you go and get Teixeira is to counteract any injury/decline that you may experience from Lowell OR Ortiz. If Lowell is down, Youk moves to 3B and Ortiz is your DH. If Ortiz goes down, Lowell becomes the DH.
It's going to suck really badly come July/August when Varitek cools down, Lowell goes into his slump (have you seen his walk rates?!?) and Ortiz continues to suck.
The FO did not address the offensive side of the ball - instead they wished and hoped for rebounds from Lowell and Ortiz.
Bad plan.
