After a bold performance last week against the Western Bulldogs, Crocker's first game in charge following Dean Laidley's resignation, the Roos again opted to take the game to the Swans.
However, one area of concern for Crocker was the inside 50m stats. North racked up 43 inside 50s to the Swans' 61.
It's an aspect of North's game plan that the caretaker coach intends to work on without compromising the attacking ethos.
"We allowed the opposition far too many inside 50s, and that comes from a result of a young group being encouraged to take the game on and take a few risks," Crocker said after the game.
"So that's an area we've got to get better in but I don't want to stifle that either. So it's just trying to get the balance.
"I thought we still moved the ball well at times. We didn't have the inside 50m count that we had last week but the Swans are very much a one-on-one type of team that also work extremely hard to get back and support their defence."
Crocker added that while the Swans loss was not a bad one, he does not want the honourable defeats to stack up for the remainder of the season.
"There are some positives to come out of it but I'm really disappointed for the boys. They've been working their knacker off to try and improve and get better," he said.
"Since I took over, the way they applied themselves around the place has been spot on, I'd just like them to get some reward for the effort at some stage."
One player who was singled out for praise was Josh Gibson. He tagged Swans' onballer Adam Goodes keeping the dual Brownlow medallist relatively quiet for most of the contest while the North defender picked up 26 touches.
Crocker described Gibson's effort as terrific and he also praised Leigh Harding's effort and Corey Jones' three-goal haul in a game that only got away from North in the final stages of the last quarter.
"Unfortunately, we just didn't have enough guys to maintain it for the entire game to get over the line," Crocker said.
"As the game wore on, we got a little more tired, and couldn't maintain the work rate required to win games."
Crocker said there were no injury concerns arising from the game.
