What has Des got to lose ? He names Williams at fullback and we give it a go.....if it doesn't work then Robbo and him can switch places and we are back to what he would have conservatively gone for anyway. If Williams makes a decent fist of it then we are better off with Robbo on the wing. Sure it might mean conceeding a try (or two) before we work out Wolfie is no good, but it is worth the shot I reckon.
Even if Des gives them free reign to switch around during the game to try a few options, that'd be good. Let Williams drop into fullback on 4th and 5th tackle in defense when they are outside our 40m and likely to kick long. That way we get to use his superior kick return. When they are attacking inside our 20 then if Des feels more comfortable with Robbo at fullback he can stay there. I'd like to see Wolfie given a shot at chiming into the backline in attack, so maybe they can switch up a bit when we have the ball. Even try Bani the following week to see how he handles it in bits and pieces.
It'd be nice to see Des try a few scenarios, we've got 8 more weeks at least of this, so why not try something rather than being conservative. We never know we may discover a hidden talent.
