The guy is a 13 who can cover wing in an emergency. He's a poor full back.

This is utter nonsense. He is a world class player capable of playing at centre, full back or wing.  The fact that he played on the wing in all three test matches against NZ, when the British Lions drew the series, is testament to how highly he is rated.

By all accounts, he is one of the few players that Jones considers to be truly world class and someone who will always start when fit, albeit that his position may vary depending on the strategy.

He is also one of the best long range goal kickers in world rugby.
