A product of the Hull FC academy system Dean is a highly rated English talent, who has built a reputation as a dynamic try-machine who likes to play with the ball in hand and attack opposition defenses.
He demonstrated his credentials with impressive performances in the games Thunder were able to play in 2020 with his game management and excellent kicking game instrumental in securing a Coral Challenge Cup win over Keighley in appealing conditions.
His running game was key in wins over Workington Town and Dewsbury Rams, whilst his goal-kicking provided 38 points to the Thunder cause as they remained unbeaten up to the cancellation of the season in March.
His route to a career in rugby league was marked out early, with his family having a long history of playing the game with his father and grandfather both taking to the field ahead of him.
Starting to play at East Hull from the age of four, his career prior to Thunder saw him star at U19s level for Hull FC before spending time at Toronto Wolfpack, Doncaster RLFC and Hunslet.
