His appreciation for the game and his composure is outstanding. He never looks rattled or stressed. He has an incredible rugby brain and has good people around him. I spent time with him at Murray Mexted's International Rugby Academy before he got the Chiefs job and I was impressed. He is a good thinker but sometimes good thinkers in the game can't get the message across. He can.
I'm a big advocate of Steve Hansen and what he's done with the All Blacks and what he will do in the future. But I hope his ongoing coaching of the All Blacks doesn't push Rennie overseas. We have to retain him in New Zealand.
He obviously gives the players confidence to express themselves. Look at the tries his men scored against the Brumbies. They are prepared to chip kick within their own 22m to attempt 90m tries. Brilliant stuff.
They remind me of the Crusaders team I played in. We knew what we were good at and how to expose teams. We had a defensively-oriented game and could strike quickly on the counter-attack; simple stuff on paper but with the players we had, it was a template for a lot of success.
The Chiefs play from all parts of the field, but they work strongly in the hard-to-see areas such as the breakdown. On Saturday, that was the winning of the game. It's easy to look at that game and say "the Chiefs throw the ball around and score some great tries", but that comes from their breakdown work. When you don't see David Pocock, Scott Fardy or Stephen Moore at the breakdowns, you know you're doing something right.
The other thing I noticed about the Chiefs - and this also relates to my time at the Crusaders playing alongside Andrew Mehrtens - is that they can turn pressure into points. Knowing Mehrts could kick them from nearly everywhere gave me great comfort and Damian McKenzie is doing the same for the Chiefs.
