I don't think we'll play both Patto and Staff in the same side. Once the ball hits the ground we'd get killed on the rebound. IMo we only need one to give Simmo a breather.
As for Tivs, the SCG is probably the one ground you would want him to play on. Just tell him him to go long to the hot spot and if he is near or inside forward 50 tell him to just go long for goal. K.I.S.S. principle for Tivs this week and Terry should drag him if Tivs chips short to contests.
