Retallick and Whitelock aren't superior due to a couple of big collisions each game. They are better because they do that, and rack up stats similar to Carter and Simmons, all whilst doing things like managing to make tackles and get to their feet for a pilfer, not at any point sacrificing the line out.
Kane Douglas doesn't solve this problem. He merely shifts it to another aspect of play.
They're getting through huge amounts more work than our guys as well.
The argument that Simmons and Carter are doing their job because they're making our scrum and lineout decent is only just halfway there.
Retallick and Whitelock got through 19 tackles between them. Carter and Simmons made 10.
If you add in the 6s, the All Black trio made 26 tackles with 3 misses to our guys making 14 tackles with 3 misses. In a game where both sides made very close to the same number of tackles, we need a better workrate out of these tight forwards.
Meanwhile, people are complaining that Palu was anonymous yet he had our highest tackle count. We need our 4, 5, and 6 making a lot more tackles so players like Palu can do the job that we need them to do which is run the ball over the advantage line.
Our 4, 5, and 6 also gave away 6 penalties and a yellow card between them. They weren't just passengers around the field, they made costly errors which gave up field position and points.
