Ross Lyon’s side hauled in 17 marks from Kangaroo kicks, with 12 of those coming largely uncontested in Freo’s defensive zone.
Spurr said it was the efforts of players up the field that made statistics such as those possible.
“The backline’s performance is determined by the pressure placed on the opposition by our midfielders and forwards,” he said.
“They put great pressure on, which makes the job much easier for the backmen to perform and play their role.
“The amount of marks we take in defence is a reflection of that hard work up the field.”
Fremantle took outright third on the AFL ladder with Sunday’s win, but Spurr said the club wasn’t interested in ladder positions at this stage of the season.
“No one really thinks about that, it’s irrelevant,” he said.
“We just want to continue playing our brand of footy and keep improving.
“There are still some areas to work on in which we want to improve if we want to get better.”
The mature-age South Australian, who held the AFL's leading goalscorer after 12 rounds, Lindsay Thomas, goalless on Sunday, said Fremantle would need to bring its best effort to Simonds Stadium for Saturday night’s clash with second-placed Geelong.
“They are a great side, they’ve done it all and they just keep going,” Spurr said.
“They’re sitting near the top of the ladder and it will be a big challenge for us, but one that we look forward to.”
Fremantle ambushed the Cats with a powerful display of pressure football in last year’s elimination final at the MCG.
Spurr said the club could take a lot of confidence from that game, but that it would mean nothing if it didn’t bring 100 per cent effort on Saturday.
“We believe our best can match it with the best, but we’ve got to show up on game day and put it to action.”
