If you go on you tube there's plenty of player after match interviews in which they state that if they don't perform or in fact if they do perform that their place still isn't guaranteed. I've seen Proctor, Wilson, Garrity, Jones etc all accept this & say they are happy. They understand DC's philosophy that every game/side is different & he'll pick a side he thinks will do the job on that particular match day. I have no worries regarding players being upset or unhappy for this reason
