Tabs certainly had to "earn his way" into the side, he stood very tall today, offering a lot in the air and on the ground. seemed like Kersten & Cam had more space as well with him up forward making the 3rd tall back being responsible for someone.
I think we will have a very potent forward line with Tabs, Kersten, Cam Mac, Walters, Grey & Ballas (when he gets back), rotating Walters though the middle and Tabs through the ruck will give plenty of time for Fyfe & Mundy to cause some havoc up forward.
