I think Waghorn is to lazy to play on the wing. I get he is a hard working player, but he doesn't close down a lot or track back like Forrester, O'Halloran or McKay do. I know he needs work on his positioning, but Tav is left to do the pressuring for RW and RB. At least when one of those 3 are playing on that side he doesn't have as hard a defending shift, especially when Waggy just camps at the halfway line.
