Jeremy Finlayson has upstaged his famous namesake to boot four goals and pilot GWS to a 34-point AFL win over Hawthorn at Giants Stadium.
GWS gun Jeremy Cameron slotted two late goals on Sunday night, when the reigning Coleman medallist repeatedly roamed beyond the 50m arc and offered beautiful service to his fellow forwards.
But it was the premiership contenders' lesser lights who did the bulk of the damage on the scoreboard, with Finlayson and Harry Himmelberg combining for eight goals as their side triumphed 13.5 (83) to 7.7 (49).
Hawthorn had 13 more inside-50s than their opposition in the topsy-turvy contest, but the Giants scored with clinical efficiency and generally used the ball with better precision and purpose.
"We need to keep looking at ways to get it inside more ... but we used it well when we went in there and looked really dangerous," GWS coach Leon Cameron said.
"Those three (Finlayson, Himmelberg and Jeremy Cameron) are finding their feet again.
"We haven't hidden away from the fact they started a bit slowly when we restarted the season.
"Week by week, the three are working better and connecting better."
For Hawthorn, the loss was soured by injuries to Jack Scrimshaw (ankle) and Mitch Lewis (hamstring) in the third quarter, with both young Hawks likely to miss their clash with Collingwood on Friday night.
"We've got a five-day break, I'd say they'd both be doubtful," Hawks coach Alastair Clarkson said.
"But we came up here with our whole squad (and) we're going to need to use the whole squad."
Liam Shiels was crunched in a fourth-quarter tackle by Toby Greene, but Clarkson suggested the three-time premiership winner was not injured in the clash.
Finlayson and Himmelberg booted two goals each in the opening quarter, their side's most productive start to a game since round one, to establish a 23-point lead at the first break.
Momentum then ebbed and flowed.
The Hawks trimmed the Giants' buffer to 10 points at halftime, only for Finlayson and Himmelberg to reassert their side's dominance and make it a 39-point lead.
Clarkson's decision to send Ben McEvoy forward was rewarded with consecutive goals late in the third quarter, while a sensational set shot from Jack Gunston gave Hawthorn some hope at three-quarter time.
Cameron's two settlers, the latter coming after a courageous mark when he ran back with the flight of the ball, put the result beyond doubt.
Tom Mitchell and Jaeger O'Meara helped themselves to a combined 49 disposals, but GWS coach Cameron opted against sending Matt de Boer to tag either one of Hawthorn's ball magnets.
Former co-captain Phil Davis clutched a game-high four contested marks, while Nick Haynes, Harry Perryman, Heath Shaw and Lachie Keeffe also starred down back for the hosts.
GWS veteran Shane Mumford's first goal since coming out of retirement for the 2019 season - after he out-muscled McEvoy in a ruck contest - was greeted like a match-winning effort.
