If Leigh don't get promoted he's off. As has been said before, I reckon there has been some sort of deal done. He's probably been asked , "stay one more year help us get up , if we don't you can go" I remember reading at the time that Brierlys nose was out of joint because the rejected bid from us. Nobody wants a unsettled player, especially one so important to a side trying for promotion. Hence why I think something has been done to keep his mind on the job at Leigh.
He would be a class signing. He could have a year learning off arguably the best support player in McGuire the superleague has ever seen.

you really are blinkered with your stupid view. Brierley wanted to leave last year, two transfer requests and two leeds bids. it was the leigh chairman who asked him to give it one more year and if things didn't work out he wouldn't stand in his way.
holding to ransom?

A transfer fee for Brierley is going to be negligible anyway. It'd be welcome in Leigh's coffers no doubt but not one that's going to keep the club going or anything. Having Brierley for another year may well just that little something extra that gets Leigh promoted. If not then the £10/20k they've lost out on was more than worth the gamble.
