The Crows, who jumped into third, led from start to finish on Sunday as they continue their charge to their first finals appearance since 2017.
Young guns Riley Thilthorpe, Daniel Curtin and Max Michalanney showed the future is bright for Adelaide in the 18.14 (122) to 8.6 (54) result.
But the attention in the aftermath will centre on Lynch after the veteran forward lost the plot in the second quarter.
Lynch was reported for striking Adelaide defender Jordan Butts off the ball following a contest between the pair.
The dual Tigers premiership player viciously threw his right hand towards his opponent, making contact with Butts' head.
Fortunately for both players, Lynch failed to connect completely, ensuring the blow was minor.
Crows players ran to remonstrate with Lynch near Richmond's half-forward flank, with the 32-year-old reported by umpires on the spot.
Although Butts was not injured in the incident and played out the game, AFL match review officer Michael Christian will likely take a dim view of the behaviour.
It is rare for AFL players in the modern era to launch into a strike with such intent and ferocity.
It completed a horror half for Lynch, who failed to register a disposal, but gave away five free kicks.
Only minutes before the incident with Butts, Lynch was angrily arguing with umpires about one of the free kicks he had given away.
The former Gold Coast captain was given bronx cheers by the Tigers faithful when he finally recorded a handball late in the third quarter, then minutes later booting his only goal of the match.
In a further blow for the Tigers, forward Mykelti Lefau injured his calf in his first game back since rupturing his ACL last year.
The rebuilding Tigers (3-12) never stopped fighting, but Adelaide were intent on building on their league-best percentage.
Defender Michalanney was the surprise packet, kicking three goals playing as a defensive forward on Richmond star Nick Vlastuin.
In 59 previous AFL games, Michalanney had managed just a single goal, but took his career tally to four in just one afternoon.
Thilthorpe was the best forward on the ground with five goals, extending his career-best season to 33 majors.
Without a finals appearance since their disastrous grand final loss to the Tigers eight years ago, Adelaide are eyeing a top-four spot this season.
The Crows (10-5) sit behind only Collingwood and the Brisbane Lions - the last two premiers - with a reasonable draw coming into finals, starting with struggling Melbourne at the Adelaide Oval next Sunday.
