"It's been happening for a while. The fact he's come out and admitted it, we all knew it anyway. So from my perspective, we've got to learn to get those things right without the dives.
"Whether he took a dive or not the referees needed to come up with a better decision there. It certainly wasn't obstruction in my opinion. They've got to be smarter than that."
Back-rower Ryan Hoffman applauded Stewart's candour and admitted he would try to exploit the current rules in a grand final situation.
"Good on Glenn, for telling the truth," Hoffman said.
"The rules give players that opportunity and look, say it was in a grand final, of course you're going to take a dive. You know what I mean?
"The game is on the line and you're going to do what it takes to win. We put our trust in the referees and video referees to make the right decision.
"I certainly don't agree with diving for injuries and all that sort of stuff, I think that's a big blight on our game.
"But because the obstruction rule has been under fire and a thousand different reviews, players aren't sure any more. So the fall-back option has been, if you feel you're impeded let everyone be aware of it."
Prop Ben Matulino said every side had players who tried to manipulate the rules and referee's processes to their advantage.
"Heaps of people do it," Matulino said. "I know as soon as there's [something like] a crusher tackle people start faking and holding their neck and then next minute they're up running the ball at 100 miles an hour and it doesn't really affect them.
"There's people in every team that do it. I'll back him [Stewart] up on his [comments]. Everyone does it."
