I'd go along with that.
I'd take Walcott to the WC because of his pace off the bench. I know he's had a poor season but he can unsettle teams and swing the momentum when brought on and used correctly.
I'm being won over by Walcott. Barring injuries, I'm thinking of Rooney, Defoe, Bent, Crouch and Walcott (who can play both up top and wide).
