Players going third-man up at ruck contests has also been hotly-debated, with more teams than ever before using the tactic.
AFL UMPIRES boss Wayne Campbell admitted the controlling umpire made an incorrect decision by paying a free kick to Nic Naitanui – who wasn't deemed the Eagles' ruckman at the contest - in the first quarter when he was blocked from the ball by Troy Chaplin.
"It's an incorrect decision. Troy's allowed to do that. If he was the ruckman, you can't block the run like that," Campbell said.
"But essentially the … second jumper, is just a midfielder so you can stand in front of them."
Hardwick was slightly miffed at the call, but said he wasn't too concerned by players jumping over ruckmen at stoppages.
"I think it's one of those ones the AFL will monitor and see how it goes. But at this stage I think it's pretty well umpired," he said.
"Overall I don't think it has a huge impact on the game."
