"It's good for our loose forward ranks, guys putting pressure on each other to fight for that starting postion," Kaino said. "Kara has always been knocking on the door, he's just needed an opportunity and he's taken it with both hands. He and Steven have been leading on the energy side of things - leading by example and it's been great for us.
"The Waratahs are a big side. They've got some big ball carriers and threats and Izzy at the back isn't small either. Physically we've got to be on point to stop that. The Waratahs do base their game on physicality."
The Blues could do worse than follow the example of the Hurricanes, who physically bullied the Waratahs in their victory last weekend. A victory would be their eighth of the season, a good result overall for Tana Umaga's first year in charge.
"The work that the coaches have put in is finally clicking with the lads," Kaino said. "The boys put in a lot of work during the June break as well. Leading into that we put in a good performance against the Crusaders. It's good that there has been a flow-on effect - I think it was a combination of having the time together and also having the confidence that our game works.
"I saw the confidence in the normally quieter guys. They were chirping up, straight away I knew there had been a lot of clarity work and skill execution work done. You can see it at trainings.
"There's still a lot for us to achieve in this game, to show our supporters that we are heading in the right direction and that we deserve to be in those playoffs. For us to put in another good performance sets us up for next year and also to retain that support and show people in our region that we're a team on the up."
