North Melbourne have hung on for a dramatic five-point victory over West Coast to kick off the Alastair Clarkson era in winning fashion and set off early alarm bells for the Eagles.
Last season's wooden-spooners seized control of Saturday afternoon's clash with an unanswered six-goal burst in the first half and withstood a late Eagles surge to seal a 12.15 (87) to 12.10 (82) win in front of 21,274 fans at Marvel Stadium.
Spearhead Nick Larkey booted six goals while midfield bull Luke Davies-Uniacke (32 disposals, 11 clearances) set the tone around the ground.
No.3 draft pick Harry Sheezel (34 disposals) impressed off half-back while recruit Griffin Logue and veteran Jack Ziebell marshalled the Kangaroos' defence admirably.
Makeshift ruck duo Hugh Greenwood and Charlie Comben battled manfully in the ruck against Bailey Williams after Tristan Xerri was substituted out with an ankle injury late in the first quarter.
The Eagles left themselves with plenty of work to do after a dire first half during which they lacked impetus around the contest, moved the ball slowly and at times looked scattered when the Kangaroos surged forward.
Were it not for key defensive duo Jeremy McGovern and Tom Barrass, the situation could have been far worse.
The pair somewhat limited the damage down back while Liam Ryan (three goals), Luke Shuey (27 disposals) and Dom Sheed (25 touches) were crucial to their third-quarter resurgence.
Larkey booted the game's first goal but it was the Eagles who took the early ascendancy, with Jack Darling threading a wonderful goal from the boundary to give West Coast a 12-point lead.
But it only seemed to spur the Kangaroos on and they booted the next six goals, with only North's inefficiency around goal, plus McGovern and Barrass, keeping the lacklustre Eagles in the game.
West Coast trailed by 21 at the main break and the Kangaroos then booted the first two goals of the third quarter to take a 33-point lead.
It sparked the Eagles into action and they kicked three of the next four goals to cut the three-quarter time deficit to just 15 points, before adding the first of the final quarter.
Cam Zurhaar's second goal and Larkey's sixth steadied the ship midway through the last term but the Eagles would not go away.
Ryan and Noah Long struck in quick succession before skipper Shuey won a high free kick to cut the deficit to three points.
Curtis Taylor spurned a late chance to ice the game but the Kangaroos held on.
