If you try and do the keepers job, then you're failing at your own. Getting nervous to the point of abandoning your primary job is no good to anyone. You do your job and you let the keeper do his. If he fails, that's his fault. Trying to do his job is detrimental to you both. It's hardly going to give the keeper confidence. Also, you just don't see this happen anyway. Managers remove keepers if they think it alters the way individuals defend. That's what happens in real world.If you're a defender and you know that your keeper is sh*te and is either going to:
A) Stand still and not attempt to get to the ball when he should do.
B) Come out to try and punch it but miss.
C) Completely flap at it then f*ck everything up.
Then as a defender I'd be taking things into my own hands to ensure the ball gets cleared (which causes it's own problems IMO).
But to go back to your point, it's the defences job to make sure that the opposition don't get any shots on goal, regardless of how sh*t the keeper is
