Quite a few coaches have an 'International' clause in their contracts. If they get offered a job at International level, they can break the contract. Given that he came from Wales, we all assumed he had left for a 'better' job at Wasps, maybe he was pushed, or the salary was jokingly low at Wales?
Maybe he was not happy with our facilities or the somewhat makeshift team announced by Dai, and maybe the role he would have done this year as a result of the team announcement wasn't what he was offered?
All in all, if he leaves, the Wasps coaching setup will be a joke. Not an auspicious start to the season.
