Whatever path the Tigers take at selection, Grigg was adamant the team was "totally different" to the one that ran out for the club's losing finals between 2013-15.
The 29-year-old also dismissed the club's record against Geelong, which has seen it lose 13 consecutive clashes and 20 of the past 21.
"We're playing a totally different brand of footy, I think. We're more consistent and we've got a lot of new players," the midfielder said.
"We've shown throughout the year that our best footy has been good enough."
Grigg said superstar teammate Dustin Martin's signature had provided a pre-finals "pep up" for the team and Richmond fans, who are expected to turn out in massive numbers for an open training session on Thursday.
The idea of playing in a premiership was something the hard-running midfielder could not help but dream about after the Tigers finished top four for the first time since 2001.
"Every player probably thinks about it every day throughout the year," he said.
"It gives us a chance. If we play well enough this year and hopefully win, we've got a chance.
"We're lucky enough to play for a big club and our supporters get out most weeks (so) it'll be 90-plus thousand, which is really exciting."
