ADELAIDE coach Don Pyke believes the Crows' backline can expose Richmond's mosquito fleet forwards with their superior height in Saturday's Grand Final at the MCG.

The Tigers have had success with their unusual forward set-up of key target Jack Riewoldt being surrounded by a fleet of ground attackers.

Pyke said the Crows thought about making a change, but backed in the likes of Kyle Hartigan and Jake Lever having the pace to compete when the ball hits the deck, while also picking off anything in the air.

"That's something we looked at and considered," Pyke said.

"That's what's working for them with one tall and some other guys.

"They've got a number of guys who are not small, they're medium sized, more than capable of catching it down there.

"That's worked for Richmond and clearly that's how they are going into the game.

"We plan for it, we prepare for it and we think we've got the right way to go about it and (a), nullify it, and (b), get an advantage from it."

The Crows completed their Grand Final preparations with a light training run at the MCG on Friday morning.

"We had a good session so we're ready to go," Crows skipper Taylor Walker said.

"You embrace this opportunity.

"That's certainly the message Don and the coaches have sent to the playing group.

"We've got the most passionate and loyal fans in the competition and they've come over from Adelaide, so it's certainly exciting and we've enjoyed it so far."

The Crows are in just their third Grand Final and the club's first since winning back to back premierships in 1997 and 1998.

The minor premiers kept an unchanged side after forward Mitch McGovern was ruled out on Wednesday with a hamstring injury, while midfielder Hugh Greenwood – who had just six possessions in the preliminary final win over Geelong – was narrowly retained ahead of Wayne Milera.

"We certainly had that discussion about Wayne and he's certainly that guy just outside that is one of those ones that is unlucky to miss out," Pyke said.

"In the end, we were leaning towards Hugh and keeping an unchanged line-up.

"Generally, at this time of the year, when you get through the qualifying finals and preliminary finals, you've got the right blend and balance.

"We felt at the end of the day that Hugh brings what he brings.

"He's been pretty solid the last two weeks, it wasn't his best game last week, but we felt comfortable about that."

It's been five months since the Crows smashed the Tigers by 76 points in their one and only meeting this season.

"It's fair to say both sides have evolved since the round six game," Pyke said.

"We learn week in, week out, and after that, we went from being, after six rounds 6-0, we got sat on our bums pretty quickly the next week against North (Melbourne).

"You learn as you go through, both sides have learnt and adapted and we find ourselves in this position."
