I don't believe Todd Blackadder's coaching does anyone any good, including Dagg.
Then again the other hopeful Andre Taylor is receiving less than wonderful coaching at the Hurricanes too with similarly negative results.
Old Bugger Retallick and Luatua are undoubtedly very good players, no doubt, and they are both young although more so Luatua.
But neither has yet suggested the impact of the two players that they're aiming to replace.
My point about Vito is that although he hasn't been that great, he HAS at times shown the kind of impact required.
Messam is a very high quality rugby player, and if Reid was gigantic, he would compliment him well. But while Reid may be the most excellent player, he does not have so much physicality that the 6 in the team can lack it. Messam is good against some teams more than others, but a more impactful player may be needed.
I see your point about some of these players being young and agree, while there is also room for improvement. But on the other hand some of the older players in the pack may get worse, even by 5 or 10%. Overall it will make a difference.
That outmuscling in the first half against England was quite striking, and if the improvement doesn't happen of the current players something different may be required.
Aaron, size or players who play impactfully. They were noticeably outmuscled by England.
