He's an easy target.
He was the scapegoat for a poor England side when he was probably the best player, and the same is happening here.
Never hiding, constant trying to make a difference and actually try things, which is more than can be said for the absolute crabs around him.
It's not all negative with Rooney, but when a team is set up to almost flow through a certain player (see the England team, and us to an extent) it doesn't work if that player isn't up to carrying that burden, and Rooney just isn't that level of player anymore.
When does it not become a coincidence that every side he's played in within the last few years has been so truly insipid and slow in the attack?
