Problem has been getting size into the starting line up - the backline we were running of McDermott, Lynagh, Ryan, Paisami, Flook, Grealy, Campbell did lack size and with Petaia and Henry injured, Vunivalu not up to it and Annan still on the rise we were slim on options. Getting a genuine big bodied, explosive back in there helps unlock guys who play big like Paisami, because they get a lot more opportunity to exploit defenses worried about (or half broken by) those guys coming through.
That said, I'm not sure Daugunu entirely covers that as he is more "plays big" than being actually big, but it does help. Certainly I think he fits the style Les Kiss has been building with backs playing at pace and popping up all over the backline interchanging roles.
