My gut says JOC (James O'Connor), Beale, Cooper and Ioane are in the starting 15 for the wallabies, therefore Deans has little option but to drop Cooper back in defense. If Link had made him play in the line all season and he had improved there might be options, but on past form defending at 10 and now 12 months more of being hidden in defense, it forces Deans hand somewhat. To push him up into the line now would be somewhat foolhardy 5 games out from the RWC.
Nothing against Link, it's his right to use QC (Quade Cooper) as he sees fit, just sometimes thats the way the cookie crumbles, and the silver lining is Coopers counter attacking brilliance.
