The Collingwood defender rates himself a “pretty slim chance” of being named an emergency this weekend, so instead he has found a sneaky way to run onto the MCG and be part of the action — or at least the entertainment.

Rounds will compete in the traditional 100-metre sprint at half-time of the blockbuster decider between the Magpies and Geelong.

While the 20-year-old backs his Collingwood teammates 100 per cent, he is not as confident about his own credentials down the straight.

He’s hoping he can relive the days when he represented Mortlake College at athletics carnivals over the short distance.

“It should be pretty interesting,” he laughed.

“If I was a betting man I wouldn’t be backing me. But we’ll just have to wait and see.”

Rounds, who made his debut in round 15 this year and played five games, has trained with the main group of 31 throughout finals.

The Terang Mortlake export has been responsible for providing a defensive presence against Magpies crumbing forwards Jarryd Blair and Alan Didak during drills.

“It’s a good feeling to be a part of it all,” Rounds said.

“Obviously I’d like to be playing but I tried to contribute as much as I could this year.

“I’m looking forward to pre-season and a big year next year (when) hopefully the boys can do it again.”

But in the meantime, all of Rounds’ attention is on this weekend.

Collingwood escaped Hawthorn by three points on Friday to book a spot in the grand final, while opponent

Geelong did it a bit easier, beating West Coast by 48 points on Saturday.

Rounds said the Magpies had learnt a lot from the Hawks and would be trying to mimic their brand of football in the big game.

“There are a few nerves after we just scraped past Hawthorn in the preliminary,” he said.

“Taking risks is the big thing. Hawthorn was taking all the risks but once we did, we started to get on top.

“It’s going to be pretty tough. We just have to play one-on-one.”
