Were you at the game live last weekend PB, because I think his defensive deficiencies didn't really show up on television, but EVERY play he would mark inside his winger, it looked more like he was numbered up against the centre. Sure this works when there isn't much room down the sideline and the defense is cramped, but so many times he'd leave the wing wide open, twice the Bulldogs got balls clean around him, but both times were called back for forward passes (one near the line Lolesi dropped as well). It's something I think he's done his whole career.
As well, watching the game again, his dummy half running was very ineffective for a guy as big as he is, getting pushed backwards constantly while Petersen, Vaealiki and especially Grothe made some good yards. Sure he took a lot of runs, but he didn't do much to get out of our own end. His tackling style isn't too bad, but his positional defense is as bad as, if not worse, Chris Walker. I think his pushing in in the defensive line is what caused a lot of the positional errors inside him, i.e Jamie Lyon's abysmal effort.
