Despite the promising start, he never established himself as a regular selection, and in the 18 months that he spent with Blackpool he played 20 Second Division matches and scored twice. Listed for transfer at a fee of £150, Roseboom joined Nelson in August 1923 for what was to be their only season in the Second Division. They were expecting "a craftsman who works good openings for others", and Roseboom did indeed prove himself both creative and technically clever, but his workrate was not of comparable quality.

He scored 14 times in 42 appearances in league and FA Cup, reaching double figures of goals in a season for the first time in his
