For that last def spot id say yes. Why not? He will be more consistant than the likes of Heppell,Lower,Stanley,Puoplo etc. As long as your other backline players are quality, otherwise id be going someone else. Really depends who the other six you have are
Seems to be getting a bit more of a midfield run...although, worringly, it seems to be happening late in the games. Could be a ploy to get his fitness back gradually after injury and lead to more midfield time and solid scoring, but if he continues only getting rotated through occasionally and doesn't tear apart the 4th quarter his scores won't be much chop.
