They are part of a select band of footballers who have played on both sides of Australian football's most famous rivalry.
Russell started his AFL life in navy blue and has finished up in black and white, having played 116 games for Carlton.
Scotland took the alternate path, starting out with Collingwood in 53 games before playing more than 200 at Carlton.
The Blues have clearly won out in terms of Scotland's two careers. The ledger is still to be determined in Russell's case.
An examination of the 40 men who have played at least one VFL-AFL game for both Collingwood and Carlton suggests that the scales of influence have been titled in the Magpies' favour, notwithstanding Scotland's impressive career with the Blues.
The men who have played for both clubs have collectively managed more than 2400 VFL-AFL games. More than 1400 have been for Collingwood, with Carlton accounting for just over 1000 of them.
That doesn't include the Magpies' first great leader, Bill Strickland, who originally started with the Blues.
Strickland played in the very first game that Collingwood played in way back in 1892 - albeit on the opposite side, for Carlton.
But within a year he had transferred to Victoria Park and within weeks of arriving was made the club's captain.
It would be a successful reign for the man considered one of the best footballers of his era, and a superb leader of men.
There were no coaches back then and the captain's role was critical on and off the field.
And in Strickland, Collingwood could not have hoped for a more inspirational leader, enforcing discipline on the team and paving the way for success.
As The Australasian once recorded: "... for so long as Collingwood's executive and players have Strickland at their elbow, so long will Collingwood continue to be a power in the land."
He led the Magpies to their first premiership triumph in 1896, winning the VFA pennant, and he was the club's first captain in the breakaway VFL competition a year later.
Two other instances of Carlton players becoming Collingwood greats occurred with Magpie hall of fame members, Harry Curtis and Harold Rumney.
When the Blues dismissed a tall, skinny, young forward after only two games in 1913, they inadvertently gave up a budding champion to the Magpies.
Curtis went onto play 122 games with Collingwood, played in two premierships as centre half-forward and then assume the role as president a year after his retirement, holding the position for 26 years.
All in all, he would serve the Collingwood Football Club for a grand total of 36 years - and was engaged at the club in one position or another for eight premierships (two as a player and six as president).
In a remarkable letter about his career that Rumney wrote to me in 1985, he explained how Carlton had told him that he was "too old (he was 19!), too weak and too gutless - a no-hoper in fact" after 15 games over two seasons in 1925-26.
He was nothing of the sort. Far from it, he headed to Collingwood where he would become a member of the famous 'Machine' and would play in five premierships and 171 games for the Magpies.
A Copeland Trophy winner, the dashing defender would posthumously be selected as back pocket in the Collingwood Team of the Century. Not bad for a bloke overlooked by the Blues.
On the flip-side, there were a couple of Magpie greats who transferred to the Blues and for one reason or another didn't reach the same heights as they had in black and white.
Everyone remembers Mick McGuane's 152 games in black and white - as well as his back-to-back Copeland Trophies in 1992-93 – but no one remembers his three games at Carlton in 1997.
Fortunately, none of the three were against Collingwood.
Or Peter McKenna's 11 games and 36 goals with the Blues (in the No.27). Magpie fans prefer to remember his 180 games and 838 goals for Collingwood (predominantly in the No.6 he made famous).
Two other Magpie/Blues played 100 or more games with Collingwood - Ray Byrne 121 games and Craig Davis 102. Both played in three losing Magpies’ Grand Finals – 1979, 1980 and 1981.
The only players to represent both clubs who have played 100 or more games with Carlton are Scotland and Russell.
Jim Crowe and Harry Sullivan would become Collingwood premiership players - 1936 and 1958 - after originally starting their careers with Carlton.
There were other characters who played for both sides, remembered sometimes for things other than their football achievements.
Les Abbott and Les Hughson are in that even rarer breed to have played for five VFL clubs, including Collingwood and Carlton.
Abbott had been born in Collingwood, but played only the one match for the club - against Geelong at Corio Oval in Round 8, 1904 - before his solitary game for Carlton the following year. Then came similarly short stints at Richmond, Melbourne and South Melbourne.
Hughson, who described himself as "a tram footballer", played one game with Collingwood in 1927, kicking a goal against Hawthorn in Round 13 before stints at Hawthorn, Carlton, St Kilda and Fitzroy.
"We weren't mercenary, but we had to play to live in those days,” Hughson once said. “Players were forced to shift from club to club just to earn an extra quid for their family. One of the reasons I transferred to as many clubs was that when my form started to drop, I felt it was wise to move on to another club so I could keep earning a quid."
He might have been a "tram footballer" - jumping on and off at each new destination - but few enjoyed the ride as much as Hughson.
In 1938 he was appointed coach of Stawell on an offer of two pounds per week and "as much free beer as you can drink at the local pub." Stawell won the flag, but the club was forced to make new arrangements the following year. They were happy to renegotiate the deal, but the pub was no longer willing to take a loss on the big-drinking, larger than life Hughson.
In more recent times, we've seen the likes of Cameron Cloke and Chris Bryan represent both clubs.
Cloke played 21 games for the Magpies, with 36 for the Blues - including two games against his brother Travis in 2008.
Bryan started with the Blues, playing 16 games before playing 30 with the Magpies.
The tradition carries on with Scotland and Russell, who were former teammates, but are now on opposite sides of football’s great rivalry.
