I reckon one of the biggest problems is our role/fringe players can't play their role for 22 rounds (like Bail, Terlich, M Jones, Pedo, etc) - so when those guys drop off our good players also struggle carrying more of the load, although Jones and Vince have been really consistent in the middle.
Vince probably had his worst game for us today in terms of decision making, a few baffling kicks straight to the opposition, it's like our horde of poor kicking players infected the handful who are usually reliable, even Jetta shanked a short kick under no pressure, it was just bizarre
