A compelling reason to join the club: Evidence has shown that you can become a star in the NRL by playing for the Tigers. Although that does not mean you will be a star *while* you are playing for them. They have been historically good at developing players, launching them into larger contracts.
If you want to have a good career, but your path is blocked or stalling at your current club, Wests Tigers is the place to be. You can spend anywhere from 1-3 years working on your game without the pressure of failure. Once you feel you are ready to earn the big bucks, you can reach out to other clubs. Those clubs know the pedigree - ex-Tigers players can be very good. Some of the best players in the game have come through here.
When you are ready to leave, you can simply walk out the door. No one will stop you, even if you have years left on your contract. And that is why you should join the Wests Tigers. Great to develop your game and use as a stepping stone to greater heights.
You may feel bad for a short while after leaving them high and dry, but there is a good chance your new club will have someone who did the same thing. They will rationalise your decision, saying it was their fault, not yours - they made you train too hard, or not enough, or they have too many home grounds, or one fan gave you a hard time because you bottled a game - it doesn't really matter the reason, because all that matters is that you are set for the rest of your career. Enjoy.
