No sooner had the final whistle sounded in the Chiefs' 50-17 victory over Fijian Drua did planning for the Super Rugby Pacific table-topper's next clash begin - an eye-watering match-up against the Crusaders in Hamilton.
On Friday, the Chiefs consolidated their place as the team to beat in Super Rugby this year, as a rotated side ran in eight tries to notch a half-century of points and secure their eighth win of the season.
Next, though, comes a rematch against Scott Robertson's Crusaders - who'll be out for revenge after an upset 31-10 defeat to McMillan's men in the season-opening match.
The Chiefs' week one feat is made all the more impressive by the fact they managed to defeat the Crusaders in Christchurch and will head into the rematch with home advantage.
But, as the six-time reigning champions look to square the ledger next Saturday, the Chiefs expect a strong response from the Crusaders.
"Every time you play the Crusaders, it's a big game," said McMillan. "The community gets excited, the media get excited, we certainly get excited and I'd imagine they do too.
"We always want to be playing those tough games, those derby games.
"With the Crusaders, you have to sit back and admire what they bring to the table. We know that generally when you get a win against them, they bounce back really strong.
"Getting to play them at home will be a special occasion."
After their first eight games, the Crusaders sit third on the Super Rugby Pacific ladder - with six wins and two defeats. The Brumbies separate the two leading Kiwi teams.
Meanwhile, McMillan also paid tribute to the Chiefs faithful who braved atrocious weather to see more than 10,000 pack into FMG Stadium on Friday.
In an age where Super Rugby crowds are sparse at best, Hamilton has shown more than once what it means to support their side.
The Chiefs' coach, though, wants to see a full house when the Crusaders arrive next weekend.
"I really want the thank the crowd who came out tonight. Given the conditions, I probably didn't expect that," McMillan said.
"They're always worth points to us. It was great to have 11,000 tonight - it would be better to have 21,000 next week."
