Clark said the RegionalOne BFL should follow the lead of AFL and VFL in having four players on the interchange bench to improve the spectacle and protect player welfare.

Balben North City led Saturday's match by four goals mid way through the third term, but injuries to Christian Philpott (hamstring), Ross Pattison (calf) and Nick Lawrance (back) left the visitors with little room to move when the Cobras mounted their challenge in the final term.

"Why not have four on the bench? Every other grade of football has four: the AFL, the VFL, even our (Ballarat Football League) reserves have four on the bench," Clark said.

"We've lost two or three games because we've had no one to bring on in the last quarter. We had no rotations and, because we don't have the bigger bodies of our opponents, we rely on those rotations through the midfield.

"If you want a better spectacle of good, contested games it would help. You don't want the bench to decide matches."

Ballarat Football League operations manager Aaron Nunn said the BFL clubs had previously resisted moves to increase the size of the interchange bench due to the added cost involved. He said, with North City only recently re-admitted to the league, Clark may not have been aware of the earlier debate on the issue.

Bacchus Marsh coach Dion Miles said he sympathised with Clark's position but did not support extending the interchange bench.

"I'm of the opinion the 21st player in the team usually only gets 45 minutes of game time and, if the 22nd player gets less than 45 minutes, he would be better off having a full game in the seconds," Miles said.

"I sympathies with Aaron. We had a similar situation with a number of injured players against Melton South, and maybe that's happening more this season because the grounds have been harder."
