All four new faces in the backline played their part in running the Stormers ragged, with Tim Nanai-Williams (158 metres and eight defenders beaten) especially excelling in his first start. Damian McKenzie looked a livewire at fullback, Bryce Heem saved a try at one end and set one up at the other, while Brad Weber zipped the ball about for the full 80 minutes.
But perhaps the most impressive aspect of the attacking outburst was the fact it arrived without anything resembling a solid base. After being such a strength in the loss to the Highlanders, the Chiefs' scrum was consistently steamrolled during a torrid first half.
Improvements were made in the second spell and parity was almost restored but, with the Sharks also imposing at the set piece, those improvements will have to continue throughout the week.
"[Last week] we dominated in that area and got two penalty tries from it, but lost," Rennie said. "This week our scrum was under pressure until late in the game, but we won.
"Obviously it's an area of the game we'll have a bit of a look at and try to be better next week against the Sharks."
Aside from the scrum, the only other concern to emerge from the match was a potential injury problem in midfield. It would be a shame, given the fluid way the whole backline linked, but both Nanai-Williams and Sonny Bill Williams could potentially miss next weekend's encounter with the Sharks with injuries.
Whichever combination is called upon, Rennie knows his charges must avoid what happened the last time they put together a rampant attacking effort, when the 40-point romp over the Crusaders was soon followed by a limp outing against the Highlanders.
"The win was massive for us ... We're pretty happy for that but it'll count for little if we don't back up."
