I agree that the sum of the Brumbies' parts is mach better than the individual parts, and I don't expect the Brumbies' players to dominate the Wallabies. OTH I also think it is unfathomable that the Tahs do dominate the Wobs. Apart from Folau and Hooper, who from the Taha would people include in the same cohort as Smith, Roff, Larkham, Gregan and Mortlock? I certainly wouldn't be putting the likes of Kepu (close maybe), Robertson, Dempsey, Hanigan, Phipps, Foley or Beale (again close) in that class of player.
And the sum of their efforts in Super Rugby this year would not support a contention that they should be kept together because as a unit they were performing to the highest standards.
