I've seen a lot of people say that his passing is dreadful. It's not the best I've ever seen, but it's not terrible either. Thing is, it's a different kettle of fish having to be on the ball in the full back position as opposed to centre half. At right back, there's greater emphasis on playing attacking balls and generally you're tighter to the line and under more pressure. At centre half, providing you have a midfielder that's prepared to show for the ball, you always have an easy option. It's why someone like Vidic, who isn't great on the ball, can still do a good job of keeping it.
We need to end this odd fixation with picking centre halves at right back purely for their height. No other top sides really do it.
