WHILE opinion among AFL clubs appears unanimously against the new substitute rule being trialled in the NAB Cup, North Melbourne coach Brad Scott says he is happy leaving the rule in the League's hands.

The NAB Cup rule, which restricts teams to two interchange players and two substitutes, has come under fire from players and coaches who have blamed the rule for pushing players to exhaustion.

Scott said it was important for coaches to be consulted during the rule-making process, but that their opinions should not be seen as the deciding factor.

"Coaches are always going to have input into [rule changes] and they're going to have their opinion," Scott told radio station SEN.

"But we're very short-term in terms of the rules because we're thinking about next week and the week after.

"The AFL, to its credit, is thinking about the game as a whole and what the game is going to look like in five to 10 years time.

"Coaches shouldn't be coming up with the rules or having a huge influence on the rules because they're always thinking about themselves and thinking about the short-term."

Scott, in his third season in charge of the Kangaroos as senior coach, said coaching - more than rule changes - had changed the game as a spectacle.

"Nothing has changed the game over the last 10 years more than coaching tactics," Scott said.

"The AFL and the rules committee, are charged with the responsibility of making sure the game progresses and is still a great spectacle for the fans and that it's something people still want to turn up and watch.

"If you look at why more marks are being taken, why we're kicking longer to contests, that's purely as a result of coaching tactics. It's got nothing to do with rule changes and it's naïve to think that rule changes have even had any influence on that."
