Notice to Beavo: Putting "notice to Ian Schubert" in your title achieves nothing. This forum is not Schubert's inbox.
As for the conspiracy, Gasnier may have just had enough. He will never be as good as he was in his peak, and as a competitor at the highest level, he probably has too much pride to run around as an above average to good centre for the the next three years after being a superstar earlier in his career. Besides that, he won a grand final last year, and next year Saints will be transitioning to a new coach, and consequently adapting to the new coaches structure and system.
Who can blame an older guy who has already done these readjustments plenty of times, from wanting to do it again?
