McMillan said the 37-5 win over Northland on Friday was an important one for their semifinals aspirations in the ITM Cup Championship.
"We were mindful of them being a banana skin for us. We, obviously, have aspirations for this season and they could have really slipped us up," McMillan said.
He was really happy with the bench players on Friday who came on and made a big impact, in a match which saw the Steamers score all four of their tries in the second half.
The Steamers now have a four win-four loss record this year, which is a big improvement on their past two seasons. However, McMillan was quick to play down their improvement in results.
"I think a lot of people are happy we have four wins out [of eight games] but my expectations for the team are higher than that ... it is nice to still be in the hunt for the semifinals but if we want to be real contenders we need to be a bit higher than a 50 per cent win rate."
He added they were making good progress though in getting a winning culture back in the team.
McMillan, who is in his first year as Steamers coach, has plenty of experience coaching in Wellington during recent years and he said he was looking forward to going up against plenty of his old friends this weekend.
While the Steamers are struggling with injury, they have a welcome nine-day turnaround until their match against Wellington on Sunday in Tauranga. The Steamers have two games left to play in the regular season.
