In the discussion of potential YCs from this match, nobody has yet identified Ben Alexander as a contender. I'm not saying he is, but there are a hell of a lot of rugby fans who don't rate him in the set piece.
Brumbies will need to be a lot sharper than they were last week. The Reds will have something to prove after they held the Rebels quite easily when they had equal numbers on the field (and for some time after being reduced to 14). Their form in that game wasn't anywhere near as poor as the scoreline might indicate. The battle at set piece could go the Reds way, and that could go a long way to gaining a win for them given the apparent difficulty sides are having turning over the ball under the new laws.
A six day turn-around including the loss of one day traveling won't do the Brumbies any favours.
Team-wise, I can see Cusack and McCaffery swapping roles at times. Both have been playing strongly and have been good over the ball. Hopefully, the rhetoric about playing more attacking rugby is there to be seen this weekend.
