Scott is on the league's new competition committee, which will have its second meeting on Thursday in Melbourne.

AFL football operations manager Steve Hocking and his staff have spent the last couple of months looking at the congestion issue.

They have trialled proposed rules in match simulation, using Hawthorn and Brisbane as guinea pigs in separate training sessions.

The Lions had their match simulation last weekend, with AFL umpires in charge and several league officials observing how potential rule changes worked.

Brisbane coach Chris Fagan is the other current AFL senior coach on the competition committee.

"It (congestion) will be there somewhere - it's a really valuable discussion to have," Scott said of the meeting agenda.

"There have been a lot of good theories put forward and now those theories are going into some clinical trials, if you like.

"So we'll be able to see some of the results from that tomorrow, hopefully."

Scott is encouraged with the debate around the congestion problem and the range of potential solutions.

"I'm glad the AFL is going it - it's a great opportunity ... to look at a few new rules," he said of the rule trials with Hawthorn and Brisbane.

"There are a lot of things being discussed about how to improve the game, but until there are actual trials, then it's very difficult to evaluate them."

Starting some players in set positions at centre bounces and larger goalsquares are among the rule changes being floated to help combat game congestion.

The AFL has said that any rule changes will be in place by October.
