As I see it I dont think the Brumbies performance has anything to do with Rea, this is due to the players.
Ideally, to fix the problems at the Brumbies would require a massive clean out and not just some of the players.
As I have said elsewhere - I dont feel sorry for the Brumbies but I do feel sorry for their supporters because getting massive changes at a team usually only come about when massive beatings like the one the Brumbies got tonight happen and happen regularly. Otherwise if they only just get beaten they can bring out the old "we are building" or "we are almost right" etc which is fair enough for the Rebels but the Brumbies for all their experience this isnt an excuse. Plenty of pain for Brumbies supporters if they want changes, it's only going to come if their team is getting smashed week in week out for a bit.
