Walker is a time bomb. He has changed his style because of a knee or hip problem. Probably more mental. He had a string of off the track incidents in NZ that he eliminated when he first got to Oz but they soon returned. Too big too soon yet again. Botched his second marriage (for reasons you will not believe!) and then supposedly hit rock bottom again to which he explained on a independent doco which was tacky to say the least. The stipes have been on his case too - that was the real reason he took his last "break" - not the head knock issues he stated to the media. As I said a ticking time bomb who seems to spoil every opportunity. Just look at his relationship with Hayes now. As David said: "Michael has always liked hard work - he had just never experienced it before".
