There's a tingle of anticipation whenever you settle in to watch them play, at odds with the odds they have had to overcome.
Rennie not only needed a new coaching team after Smith stuck with the All Blacks and Tom Coventry headed overseas, but he has to put new teams together on the field. The injury list is staggering: Brodie Retallick, Dominic Bird, Nepo Laulala, Nathan Harris - deep breath - Tawera Kerr-Barlow, Pauliasi Manu, Augustine Pulu, Anton Lienert-Brown, Andrew Horrell, Shaun Stevenson.
"When someone falls over we've got to pull tighter together," is how Dave Rennie puts it, and you'd better believe it.
The man has the midas touch. Michael Leitch plays so well for the Chiefs it makes you wonder if the young man who headed to Japan and embraced the way of life there could have been an All Black.
Rennie lures rising test class such as Laulala, brings back blokes like Hika Elliot and Stephen Donald, finds stars that other people miss, takes some of the best emerging talent and hones it, and gets a one-time provincial hopeful like the pocket rocket Brad Weber to become a test candidate. (Perhaps the one big hole in the plan so far is an inability to turn Aaron Cruden into a world class goalkicker)
The individual highlight on Saturday night was Cruden's backwards pick up on the run to keep a move going for a Toni Pulu try. But there were so many highlights with Charlie Ngatai - a prime example of the Rennie effect - and the whiz kid Damian McKenzie in the thick of it.
The big Dave Rennie question is this: how will his future be affected if Steve Hansen does a little u-turn and, not unexpectedly, stays in charge of the All Blacks for the next World Cup.
Rennie has often talked about his desire to coach overseas and the advantages of doing that. His Chiefs contract ends next year, and he would have been the front runner to step into Hansen's large shoes. It's not just about the Rennie results, it's the way the Chiefs play and the types of players they like.
Hopefully Rennie gets a chance to bring his magic to the All Blacks one day.
