His connection with the Magpies and his pathway to the club is both heart-warming and extraordinarily rare in an era where footy hopefuls end up wherever they are drafted - regardless of where they live or who they might barrack for.
That Seedsman ended up in black and white seemingly was almost fated - with a dose of perceptive recruiting and family persuasion mixed in.
The running defender happens to be the great-grandson of former Collingwood and Fitzroy player James ‘Jim’ Sharp, who would also become one of the Magpies' most admired administrators.
The fate might have been in the stars.
The perceptive nature came from Collingwood recruiting chief Derek Hine, who had identified a good talent ahead of the 2010 national draft, who played for Eastern Ranges and Caulfield Grammar.
The persuasion came at almost the same time as Hine was seeking this kid's phone number. President Eddie McGuire had given an address at a Brighton nursing home when one of the residents told him the club should recruit her grandson.
She told McGuire that Seedsman had a direct link to Sharp, who had also been president of Collingwood for 12 seasons.
Not only that, Sharp was the only VFL-AFL president to actually play in a match while he was still in office.
The Seedsman-Collingwood recruiting match was one almost made in football heaven as Hine received a phone call from Joyce Sharp advising him about her grandson, and the Magpies took him with pick 76 in the draft after the 2010 flag.
Even more of a coincidence was the fact that Seedsman had actually done work experience at Collingwood a few years earlier.
Two-and-a-half seasons on from the draft, the kid with the Collingwood pedigree is steadily making his mark after 21 senior games - two more than his great-grandfather played in black and white, although Sharp also managed 161 with Fitzroy.
It's fitting that Seedsman is in the midst of his best season in 2013 - exactly a century on from the year in which his great-grandfather first became Collingwood president.
When speaking with The Age recently, Seedsman expressed his pride in his great-grandfather's black and white legacy.
So who was James 'Jim' Sharp, and what sort of impact did he have on Collingwood and on the game itself?
The answer is clear and significant.
Sharp was a "brisk moving (centre) half-back", according to The Encylopedia of AFL Footballers, and one of the best defenders of his generation.
But the bulk of Sharp's VFL matches - 161 of 177 - came with Fitzroy, the suburb in which he was recruited from. Only 18 of those games would come in an injury-ruined but popular stint with Collingwood.
According to Michael Roberts' A Century of the Best, Sharp "was renowned as one of the best and safest marks in the League, and also as a player who loved to run with the ball and deliver long, clearing kicks." His great-grandson also likes to run with the ball and power it long into attack.
Sharp first played for the Maroons in 1901, kicking two goals as a forward in his debut match before a move to defence.
Sharp would play in four successive Grand Finals with Fitzroy – 1903-1906 - two of them winning ones.
The first was against Collingwood, in 1903.
Incredibly, he wouldn't remember too much about it. After the Magpies won by only two points - when a late kick from Maroons' captain Gerald Brosnan narrowly missed - Sharp collapsed from "sunstroke and heat apoplexy". He would not regain consciousness until 9.30pm.
Sharp was listed among the Fitzroy best players in the 1904 premiership win - some adjudged him as best afield - and he also played in the 1905 flag side as well.
The Lions list to Carlton in the 1906 Grand Final.
His career with Fitzroy came to an abrupt end after in the middle of 1910 after he was dragged into an internal dispute at the club.
He had been club's captain from 1908-1910, as well as captain of Victoria.
Collingwood coaxed Sharp to make a comeback for the 1911 season, with one sports publication at the time saying he was one of the most respected men in the game.
He played 14 matches for the Magpies in his first season, and was a member of the club's losing Grand Final team.
Such was the respect with which Sharp was held in his short career with the Magpies that the players voted him in as captain for the 1912 season.
Magnanimously, he knocked back the honour bestowed on him out of respect for the club's new coach 'Jock' McHale.
It was a selfless moment that summed up Sharp's character and commitment to the team and would unite him and McHale as friends for life.
The first Football Record of 1912 - the inaugural edition - said: "Fine sportsmanship was shown at the Collingwood players' meeting for the election of captain and vice-captain. Jim Sharp was nominated for captain but declined and proposed J. McHale, who he said deserved the honour and he would do all in his power to assist him.
"Dick Lee, last year's vice, then proposed Jim Sharp for the position. When such fine sporting feeling is shown at the outset, a pleasant and happy season is assured."
Sadly, for Collingwood, and for Sharp, it would not be a happy season. Injury ruined Sharp's year and all but ended his career. Inconsistent form in McHale's first season as coach meant the Magpies missed the finals.
Sharp's injury came six days before his 30th birthday, when playing against St Kilda at the Junction Oval in Round 3, 1912.
As the Argus reported: "During the second quarter of the game ... Jim Sharp, back man in the former team, came into collision with (Bert) Pierce, the results being that he sustained a fractured tibia."
The injury was a horrific one. It was said that his shin bone was "broken halfway through".
The Herald recorded: "It helped to rattle the team ... Collingwood and the football world, generally, were similarly shattered. (It) may have the effect of keeping him out of the game forever."
Sharp was rushed to the Alfred Hospital and six weeks later newspaper reports suggested he was still confined to bed.
The plaudits were many for his courage upon his retirement as a player.
The Football Record stated: "He is fair and dashing, full of ability, with a due sense of the responsibilities as a footballer. It's men like Jim Sharp who bring honour to the pastime."
The Herald added: "Every footballer and admirer of this manly, dashing player will sympathise with him in his misfortune."
The club's annual report would say: "His short run in the Collingwood colours had just been long enough to make his fellow players appreciate his many sterling qualities."
Those qualities would be utilised off the field in the coming years. He was appointed president in 1913 and would hold that role until the end of the 1924 season, presiding over two premierships.
A Century of the Best praised his qualities, saying "his intelligence, integrity, and knowledge of the game guided the club smoothly through the war years and into the dual successes of 1917 and 1919."
When Collingwood was left a player short for its game against Geelong at Corio Oval in Round 15, 1917 - after Les Hughes failed to make the train trip - Sharp was called upon to take the field.
At 35 years and 101 days, Sharp lasted only a few minutes of the match before he suffered a serious knee injury.
He would never play again, though he would play just as an important part in the club's future off the field.
Sharp, who ran Allan's Photographic Studios in Collingwood, held onto the Magpies' presidency until the end of 1924.
Fittingly, he resigned after a game against his old side, Fitzroy, with the Argus recording: "Mr Sharp, in thanking the Fitzroy committee for their good wishes, said he had been a long while associated with the game, but had made up his mind to retire and had handed his resignation to the Collingwood committee."
Collingwood mourned Jim Sharp when he passed away in October 1945, aged 63.
Now, almost 70 years later, Sharp's great-grandson is still serving the Magpies. And judging by what he has delivered so far, the link is going to last for some time to come.
