Under-fire Brisbane coach Justin Leppitsch has lashed out at the AFL concessions handed to expansion clubs after his side’s devastating 138-point loss to Adelaide.

Leppitsch is facing further questions about his ability to lead the dismal Lions to success after they conceded the highest score of the season in their 27.15 (177) to 6.3 (39) thumping at Adelaide Oval.

The third-year coach deflected questions about his job security after Saturday night’s game. saying they were for the Lions’ board to answer.

But he took aim at the AFL over the concessions handed to expansion side Greater Western Sydney, whose success this year could not be further from Brisbane’s lowly performance.

“We’ve been given nothing as a footy club,” Leppitsch said.

“GWS bought Heath Shaw and (Shane) Mumford with the extra concessions they got with cash.

“You’ve got to understand there is a system behind what you see out there on gameday.

“(Some) get more concessions and some don’t.

“Coaching and what I do is a very important part but it’s still only one part of a very big picture that we play in this game to win an AFL premiership.”

The Lions managed just one goal compared to Adelaide’s 13 in the second half of their capitulation to a far superior Crows outfit.

Describing his inexperienced players as boys against men, Leppitsch admitted he feared the effect Brisbane’s massive losses were having on senior stars such as Tom Rockliff and Dayne Zorko.

“They’ve been at this club a long time and we haven’t given them a lot of success,” Leppitsch said.

“They’ve got to hold up a lot. They’ve got to play with a lot of young kids and it must be draining for them to do that week-in, week-out.

“As a footy club, we’ve got to protect them as much as we protect our kids because I’m sure they’re hitting the age now where they’re thinking ‘well, where’s this club going?’ as well.

“I don’t think they’re questioning their future here but we just have to keep reminding them that good times are going to come.”
