Wigan's recruitment in the front-row over the last few years has been a parade of mediocrity - Pettybourne, Flower, Dudson, Clubb, Mossop, Tautai.
And yet they've still managed to be competitive for the big prizes, because they play within a system both in attack and defence which doesn't ask those players to do more than truck it in, find the ground and hit anything that runs in their general direction. Credit for that goes to a much maligned coach. He's got a forward pack which is much better collectively than the sum of its parts.
