I think, when young and looking for some game time, almost every back needs to see himself as a utility.
Take Mortlock as an example, he started off as a bit of a winger, but ended up as one of Australias enduring outside centres.
Playing in the backline's pretty much all the same isn't it? Drop the ball, do your hair, slap a forward on the arse for getting your shit out of the fire again!
