Because you need a squad of 30.
We have a very top heavy cap at Manly and I think keeping guys like Taufua and Boyle on the cheap is better business than trying to sign other players from other clubs to come and provide the same role...these two are already part of our club, our culture and can wait for an opportunity to come their way should injury permit.
Our 1st choice wingers are locked in but you could do worse than have Jorge cover an injury given his experience. As for Boyle, he has the talent, just needs a bit of luck with injury. Neither are expensive so happy days!
