A hold up player is there to allow us to move up the pitch in a quick manner unlike the name suggests. Unlike building from the back, he will receive the ball in an advanced position and "hold it up" until other players can push up to support. So what if he don't score loads of goals (which he might just given the game time), there is more to football and being a "STRIKER" as you suggest then just putting it in the onion bag.
