Clauses are not about mutuality. Any person can negotiate a mutual release.
These Logan players were already signed to the club prior to the Milford saga.
So you can hardly use them as an example
A clause can need conditions, if parties disagree conditions have been met then they'll be challenged which could be the case here, without knowing the exact clause we're all assuming.
Not sure on the legalities of u18 contracts or if they were already contracted so once again assuming, BUT both Lees are Logan boys and look like staying so they can't be too pissed about Milfs treatment can they?
Your whole post was full of assumptions to suit your bias, not facts.
