Until JJ starts playing at a level that puts him at about our 4th or 5th best middle forward in terms of whole of game performance, he has to be in the team, he has earned it, and we don't have another player at the moment that does the vital stuff he does as well as he does it.
But he isn't the link man needed for that type of system, at least not to the quality of Yeo or Radley. Jimmy G was a good link man from prop, but I don't see Thommo or TPG being that good. When we want to do an expansive play we need a few different options. I wonder if Cook might provide some answers there, he is an unknown for me, but has some pretty big talk around him.
Alternatively with guys like Thommo and TPG (and Vaughan) charging down the middle, we should start getting some more offloads. With some genuine speed and evasion in Burton, Dufty, Naden, Hetho, and of course JAC, maybe we should be focusing on winning quick PTB is looking for gaps/2nd phase play in the middle third. Keep the expansive plays/backline spreads as a variation.
