I don't see Murphy as a number 10. He's a head down and run with the ball type player, not someone who can create with deft passes and touches like Tomlin or Wilson.
However, I do agree that he has the ability to be one of the best in the division, providing he has the defensive shackles of the game loosened. Perhaps a free role, a bit like Whitts had when out on the wing, like when Jones was manager. That would require a more defensively minded full back, so not Bennett.
