ADELAIDE has enjoyed living life on the edgeaccording to versatile defender Scott Stevens.

The Crows’ inconsistent form put the club in the precarioussituation of having to win the last three games of the season, but Stevens saidthe no-margin-for-error mentality had contributed to Adelaide’s form reversal.

“The simple maths of making the finals has played a part,”he said.

“We had a [three-day] break and then there were only threegames to go, so there was nothing to do but set ourselves for the last fewgames.”

“We put ourselves in the position where we had to win thosethree to make finals and the job's not done yet. We’ve had two good wins, butit all means nothing if we lose this week.”

A win over Collingwood on Friday night would seal Adelaide’splace in the eight, while a loss would leave the Crows sweating on the outcomeof other games.

Brent Reilly will be available for the must-win clash afterhaving his rough conduct charge thrown out by the match review panel. MagpieAnthony Rocca is also free to play after accepting a reprimand for a strikeon Adam Goodes.

The Crows are fast-becoming the night owls of thecompetition having claimed eight of their 11 wins under lights.

Only two teams have beaten Adelaide this season in gamesplayed at night, but unfortunately for the Crows, one of those teams isCollingwood.

Stevens fronted the media on Monday, but it was an injuredstar that identified Adelaide’s potential secret weapon.

“Nathan Bassett, our resident statistician brought that oneup. I’ve got no explanation for that whatsoever,” he said.

“Maybe we just like the yellow footballs.”
