[3] However, Sunderland manager Bob Kyle decided to give Seed a second chance, this time playing him at inside right instead of centre forward in a North Eastern League match against Wallsend.

[3] Seed spent the 1914–15 season playing in Sunderland reserves,[3] he scored plenty of goals as the team lifted the Durham Senior Cup.

[3] With the cessation of hostilities, Seed played a Victory League match for Sunderland against Durham City in 1918, however his lungs were weak and he had a poor game.

[3] On the strength of that performance the Sunderland directors decided that Seed's wartime experience had finished him as a footballer and let him go, although they did not put him on the transfer list as they thought his lungs were too damaged.

[3] Seed's football career was rescued by former Wales international Haydn Price, the manager of Welsh non-League team Mid Rhondda, who were based in the town of Tonypandy.

[4] Seed's good form attracted the attention of Tottenham Hotspur manager Peter McWilliam and in January 1920 he signed for the north London side for a fee of £250, a move which caused some antagonism amongst supporters in Tonypandy.

[5] After initially playing five games in the reserves Seed got his first team chance with Spurs, making his debut at inside right and forming an immediate understanding with the legendary, diminutive right winger Fanny Walden.

Just two months after getting his cup winners medal Seed was called up for the first of this five England caps on 21 May 1921 against Belgium, he never got a long run in the international side, playing his final game in April 1925.

Seed's reaction to this was to ask to be released by the club at the end of the 1926–27 season and after looking like taking the player/manager job at Aldershot, he eventually signed for The Wednesday in a part exchange deal involving Darkie Lowdell and a cash adjustment paid by Spurs.

During the first part of the season Seed was asked to play in numerous different positions by manager Bob Brown as Wednesday struggled in the First Division.

At that stage Seed was made team captain with existing skipper Fred Keen being dropped, Ellis Rimmer was bought from Tranmere Rovers and these changes triggered an amazing recovery.

After damaging the ligaments in his right knee in a match against Newcastle United at Christmas 1930 he realised his playing days were numbered, but he did not retire until the end of the 1931–32 season.

Seed commenced the job at £12 a week but within a short time Arsenal were forced to abandon their plans after being told by the Football League that they were acting unlawfully.

Following two lower mid-table finishes, Charlton, with key defenders missing through injury, endured a poor start to the 1956–57 season, losing their first five matches, before Seed was sacked on 3 September 1956.
