Not sure if Croker really has to change his playing role and style that much , high work rate , efficient delivery , good support play ., seemed to be just fine doing this last season . Only limited attacking options in any set plays and based on Manly " current playing structure , probably best to just concentrate on what he has been doing well . A little bit of variation O K but again would not seem a real priority for him to change much at all , just keep on being healthy and busy and a genuine competitor .
