Richmond forward Tom Lynch says those doubting teammate Jack Riewoldt's ability to influence Saturday's AFL Grand Final only need to remember last year's decider.

Riewoldt hasn't had more than six disposals in any of the Tigers' three finals on the way to the Gabba premiership clash against Geelong.

The 31-year-old, who booted four goals against the Cats in round 17 this year, went goalless in the semi-final win over St Kilda and could managed one major in last week's preliminary final victory against Port Adelaide.

Lynch is far from concerned about his forward partner's form, saying the stats sheet is not reflective of his influence on the game.

He also made sure to point out the two-time premiership winner and three-time Coleman Medallist delivered when it mattered in last year's Grand Final win over GWS.

"He kicked five last year in the grand final," Lynch said.

"If he did that again it'd be nice.

"But, no, Jack's had a really good year and he was super on the weekend.

"Just his contest, he was outnumbered a lot and brought the ball to ground. I thought he played a really good game on the weekend."

Lynch has also praised Riewoldt's support and influence on him since his arrival at Tigerland in 2018, saying he and captain Trent Cotchin highlight the selflessness which has been a cornerstone of Richmond's success in recent years.

"Jack's been amazing for me. Ever since I've walked in the footy club he's just been massive support for me I couldn't thank him enough," Lynch said.

"He's just a massive team player.

"He's obviously a three-time leading goalkicker, tells me that every now and again, but he's all about the team and you know that he'll do anything he can for the team.

"Just shows you that the highest profile players, they care about the team and that's what gets results."
