The Kangaroos are in a far different position to this time last week, where widespread criticism of their performance in St Kilda's 104-point flogging cast a shadow over what they could produce in their clash with West Coast.
Arocca revealed it wasn't the case in-house, and that Scott had handled the situation as he hoped he would.
"Just the response I could see in the eyes of the players after Brad spoke to them [after the game], suggested to me that we were always going to beat West Coast," he said. "Then again, you never know for sure.
"It was a measured, calm, thorough assessment of what had happened. It was a clear, concise and forthright statement of what we needed to do.
"From my point of view, not much changes about Scotty. Whether he's on a radio station, television station or talking to a member - he's measured, he's calm.
"I've watched him in the box and I've been not only pleased, but not surprised by the way in which he conducts himself."
Arocca agreed that Scott had been under a lot of external pressure for someone so early in his senior coaching career, which made his reaction all the more admirable.
In fronting the media ahead last Friday, Scott spoke of the club's embarrassment but took full responsibility for a game plan he believed would eventually prove very successful.
It was an attitude he had carried for the entire week.
"He didn't buckle. I didn't see him flinch. I didn't see him blink. From everything from the very robust criticism from media people - some ex-North Melbourne people - to dealing with his players, the demeanour around the place ... it was just great," Arocca said.
"There was nothing in the way of what we spoke about that was any hint of anything other than, 'These things happen'.
"We'd be kidding ourselves if we didn't think that we were going to get some exhilarating highs and some devastating lows in any journey, but I just like the way that he has unbreakable, unshakable confidence in what he's doing, how he's doing it and where he's doing it."
Arocca conceded that North's administration had considered its potential hurdles, particularly those that a young coach with a developing list could face.
"Football is about preparing yourself for the unexpected," he said.
"There is no doubt that if you support this club, having to watch them lose the way they did was heartbreaking.
"That's the beauty about footy. The siren goes, the game finishes and if you're any sort of club, any sort of organisation, you reload and go again."
North will search for its second win of the season when it hosts the Sydney Swans at Etihad Stadium on Saturday afternoon.
