The premiership coach paused a moment to admire his forward line, while positioning his teal-coloured magnets on the whiteboard at Glenelg Football Club.
Lance 'Buddy' Franklin, Matthew Pavlich and Cameron Mooney will spearhead the Dream Team attack, but Williams was yet to decide on just where to play resurgent Richmond star Matthew Richardson and who out of Brett Burton, Matthew Stokes and Leon Davis would get the nod in the small forward position.
Williams spiced things up when he predicted heartbreak for confident Victorian fans planning to head to the MCG on Saturday night.
"I know that the Victorian crowd are going to come to the MCG thinking they are going to win and waltz over the top of us, but that’s not going to be the case," he said.
"With the passion and the strength of commitment the players have showed already – the fact is we’re coming to beat the Vics. There will be 80,000 Victorians walking away very disappointed after seeing they’re not as good as they think they are."
Williams revealed he already had people studying the potential Victorian line-up and sorting out match-ups for the prestigious game.
With so many quality players in both sides, there’s temptation to play them one-on-one, but Williams said the Dream Team would need to employ some defensive strategies.
"I guarantee we won’t just be out there to kick 90 goals each," he said.
"There’s no way Victoria will let our forward line loose by itself and we’re not going to let their onballers just go off and do what they like. There’s going to be some players doing run-with roles, but with the quality of players you can’t just shut one person down.
"It will be interesting because Cam Mooney may well play straight on Matthew Scarlett and it will be great to see which one of those players is the best."
Williams threw a few names including Cat Tom Harley and Bomber Andrew Lovett into the mix for a late call-up and said he was looking forward to seeing another of his late inclusions, Daniel Motlop (who didn’t yet have a magnet), play in the star-studded forward line.
"With Buddy and Mots and all our Aboriginal contingent, it’s going to be a wonderful game. I was lucky enough to be at the game to see Buddy fire in the second half against Collingwood last week and then wandered down to our game to see Daniel turn it on as well," he said.
"It should be fantastic to see and all that skill and flair that those guys provide is a real reason why I expect 80,000 people there."
Williams has been involved with numerous clubs across the country including Collingwood, Essendon, Brisbane and Port Adelaide and even played for the Big V during his career.
"It’s really difficult at home. My wife Pauline is walking around in old my Big V guernsey and one of my sons, Isaac, was born in Victoria so I think there might be a few fights at home," he said with a laugh.
"But without doubt my allegiances will always be with South Australia.
"Obviously, my dad [Fos Williams] coached South Australia’s win in 1963 and I’d love to think I could be part of the group that has beaten the Big V.
"We’ve got his football at home, which is signed by all the players who played on that particular day. That was a hell of a long time ago and it’s still one of the most memorable times in South Australian football.
"Over the years, Victoria has been the benchmark of football in Australia, but now it’s the AFL and we want to show them they just play their part, rather than being the number one guys."
