Maybe he was told to do this. Look at the cross for Murray's winner Vs Dundee, he definitely didn't have zero effect.
I'm not saying it was entirely of his own volition, I'm saying that's what he did 9 times out of ten. That cross was brilliant, but he was in exactly the right sort of area that he needed to have been when he got the ball off centre back/left-winger-for-the-day Paul Hanlon. I was hoping he would go wide a lot more than he did, because - as we saw in the Scottish Cup Final - he was at his devastating best when out there.
