Thing is with Pav, Technically he's not a very good footballer, He's main attribute is shooting.
When you have someone like that in your side, the rest of the team have to work alot harder to create chances, look at Defoe's performance for example yesterday, i have never seen him run so much.
But he had no choice because he was playing up front with Pav, if he was playing up front with Crocuh Sunday i don't think we would have been doing that.
But that's not a dig towards Harrys team selection yesterday, totally understand why he went with Pav over Crouch, because of the goal threat and he knew Defoe could do a good enough job dropping off.
I do understand what your saying about, if a strikers not scoring goals ship him out, and its true strikers do need to scare goals, but i feel they need to do alot more than that too.
Look at the best strikers in the world, Drogba, Torres, Rooney, Berbatov, Etp'o... none of them are just out and out goal scorers, they do create goals to.
You could say Pav offers us what Crouch doesn't, but i feel that in some ways Crouch offers us what Pav doesn't aswell
