The big change for me has been the strategy in attack that has finally adapted from what it was over the past 5 seasons.
Because of the addition of players like Foran, Schuster, Garrett, Saab, Harper in the backline, Manly are now spreading the ball wide on far more occasions. Before that they were playing a game more tightly centred and dominated by forward play with little imagination.
I was getting the sense from Des and even Barret before him, had no confidence with the three quarters outside of DCE especially when Turbo and Walker were missing. They are now spreading the ball and you can see now that the backs are scoring most of the tries, whereas before the forwards were. They had much of the time a pedestrian backline who couldn't score tries.
Now we have speed and imagination in the backline, an improving group of forwards and consequently confidence has gone up. They are now playing like they should have been for the past half a decade.
