[Edit - There has been plenty of discussion on this point and I should just say that the stats in our last game just support what the knowledgeable people on the is forum have been saying.]
If you look at the stats, the issue leaping off the page is the lack of metres from our back row. I will exclude Brown from that statement. In spite of his lack of fans in this forum, once again he delivered when the chips are down with 121m and 31 tackles. Menawhile, Docker, Taylor and Yeo made 42,77 and 75m respectively. Manu actually did his best work for a while with 99m and 22 tackles.
I will also point out that Taylor made 57 tackles and missed 2. He did his work in defence and still made 77m, but that means somebody else can do less tackles and make plenty of runs. At the moment we are missing a back rower who busts the line (as many people have already said on here).
To illustrate this, just look at the Roosters. They had both Williams (179m) and Cordner (189m) deliver huge metres. Their props both chipped in with 122 and 130m and made 33 and 38 tackles.
I can't help but think it is time for Jamal to move to the back row (as others have said) and bring up Smith, Yeo or Blake into the centres. I think Cartwright should get more minutes but he is only young and will fade in and out as he gets used to the NRL slog. He will deliver more next season and will be best used for impact this year.
At the moment we have too many Van Der Voorts and not enough Geyers and Cartwrights.
