I much prefer Stringer for the big games, I like Cook and agree with our investment in him as the future of the club, but I think Stringer should have rotated in a bit more. Especially ahead of Young, who was just never good enough.
We really should've held on to Stringer, still the best pass around and that's what Ford needs - he's the playmaker, just get him the ball as quick as possible and let him find space. GN10, I agree that Cook's been excellent and we've played some great rugby with him, but don't think we do lose speed with Stringer in his place. Space maybe, as he doesn't tie in defenders (although Cook's not really a big sniper either), but PS gets to every ruck, makes a quick decision and fires a quick pass all day.
Edit: I agree on Matawalu though, Devoto turned out not to be the playmaker needed during the international window, hence Matawalu. He also turned out not to be a ten, hence Priestland. Or the goalkicker, hence Homer. A lot of planning and cash has gone into covering for Golden Boy it seems, I hope we aren't too reliant on him...
