Graham, 25, played with St Helens for 9 years, making his debut as a 16 year old, with many believing that he has the potential to be a bigger and better player than current English prop Sam Burgess.
Whilst it was a tough decision for Graham to leave the ESL and England, he said that the prospect of playing in the NRL was simply too good to refuse.
â€œThe decision to leave St Helens has been by far the biggest decision of my Rugby League career,â€ Graham says.
â€œIâ€™ve been on the books with Saints since I was 11 years old and I grew up supporting the Club. I love the place and I never wanted to play against them, and as such I didnâ€™t consider any other Super League options.
â€œTesting myself in the NRL is something Iâ€™ve always wanted to do, and the Bulldogs just seemed right from day one. From meeting with Todd Greenberg and Kevin Moore and also Peter Mulholland, I got a feeling that the Bulldogs are a Club heading in the right direction.
â€œThey made it clear to me that they saw me as a big part of the future of the Club and Iâ€™m looking forward, after a successful finish to my time at Saints, to linking with the Club at the end of the year.â€
For Dogs coach Kevin Moore, he sees the signing of Graham as a valuable acquisition for his side.
â€œJames is a player of the highest quality and weâ€™re very much looking forward to having him on board from next season onwards,â€ Moore says.
â€œHeâ€™s been rated among the best front rowers in the world for a number years now and itâ€™s always exciting to add international quality to your forward pack. Being the current captain of Great Britain his leadership qualities are obvious and he will be a great addition to our Club and our team.
â€œI think heâ€™s going to make a big impression across the NRL.â€
Bulldogs CEO Todd Greenberg shared the same views as the Dogs coach on Graham.
â€œOne of the things that struck me about James is his genuineness,â€ Greenberg said. â€œHe was up front about wanting to test himself in the NRL and was also up front about the qualities he wanted in the Club he was going to join.
â€œHeâ€™s obviously come through a very close-knit environment at St Helens, who have fostered him from a very young age and have done a fantastic job with him both on and off the field.
â€œThere were a number of NRL Clubs in the hunt for James and we take it as a compliment that such a fine young man sees the Bulldogs as having the right type of environment to further himself in football and life.â€
