Yeah looking at that squad the position players were super deep. 6 of them put up over 3 WAR (Well, Johnson, Rios, Glaus, Hill, and Overbay). The catcher combo of Molina and Zaun combined for over 3 WAR as well. Then you had Hillenbrand, Hinkse and Cattalanato hitting solidly from the DH/Bench.
Pitching (with Josh Towers putting up like the worst season ever) and SS (I forgot how much Russ Adams sucked) really let them down that year.
