While the likes of Ben Brown, Daniel Wells and Drew Petrie stole the headlines for their part in the 12-point win, those within the club know just how important the 24-year-old defender was to the outcome.
"Coach Brad Scott collectively has wanted us all to learn to play intercept-style football," Grima told AAP.
"Sammy typified that last week. The game was probably slipping away from us.
North was behind 33 points during the third quarter of the Elimination Final at the MCG when Wright appeared from nowhere to steal the ball away from Jobe Watson and Brendan Goddard.
"For him to win a two-on-one, intercept the ball and get it moving forward was a big turning point in the game."
After 82-games and averaging 18 disposals in 13 matches in 2014 including 23 touches and eight marks against Essendon, Wright says he’s focused on intercepting the ball a lot.
"I've been trying to get that into my game and get confidence in that area," Wright said.
"It is a scary thing to do when you're playing on some of the good small forwards.
"You realise if you leave and drop the mark, they're probably going to be front and centre gathering the crumbs.
"But it can be team-lifting and can really change the game."
The Roos can’t afford to bask in the glory for too long with Friday night’s semi-final looming large.
“We've watched Geelong closely. We've trained with them a couple of pre-seasons ago," Wright added.
"You look at Andrew Mackie, Corey Enright, James Kelly.
"Enright especially, I've looked at his game a fair bit. The way he goes about it and really helps out his teammates by coming across, we've taken a lot out from them."
