The only thing left now for the Crows, who jumped two places to 15th on the ladder, was to celebrate.
As the heavens opened, Mackay, playing his 248th and last game after announcing his retirement during the week, was mobbed by every one of his teammates after he marked and goaled at the 22-minute following a perfect spot-up from Ned McHenry.
Then it was Lynch’s turn.
Playing his last game in Adelaide colours, Lynch pouched Shane McAdam’s footpass and finished with typical skill with his last touch as a Crow and his team’s final score of 2021.
If a poll was cast at half-time to rank the best players afield, Hall would probably have featured at the top of most cards.
Sadly for Hall and North Melbourne, at least a dozen Crows would be next on the list before another Kangaroo would feature.
Hall had 19 possessions and 10 rebound-50s at the main interval, along with a truly outrageous 592 metres gained, backing up his 36, 38 and 30-disposal hauls across the previous three weeks.
Adelaide’s inaccuracy allied with Hall’s rebound, penetration and composure ensured the margin didn’t completely blow out.
Evergreen Hall has been a rare bright light in a season of lows at Arden Street, moving from his customary wing to a deeper post across half-back and fashioning arguably the best season of his 10-year AFL campaign.
McAdam had the reduced-capacity Adelaide Oval crowd on its feet when he soared for a late mark-of-the-year contender midway through the opening quarter.
Giving himself a run-up virtually from the fence, McAdam read Darcy Fogarty’s entry perfectly and leapt high above Aiden Bonar and Goldstein, while leaving Luke McDonald for dead and snaring a beauty, before slotting truly to give Adelaide an early lead.
In the second term, Tarryn Thomas silenced those same fans by pulling down a grand mark which was every bit as acrobatic as McAdam’s.
With Billy Frampton bearing down ominously, jet-heeled Thomas jumped above Jordon Butts and Eddie Ford to pouch his fine retort.
But unlike McAdam, Thomas, who sneaked forward and received the one-two from Jy Simpkin, snapped his hurried attempt out on the full, well and truly epitomising the surprisingly large gulf between the two also-rans.
