All players have deficiencies and I think you have identified Nash's. However, my impression is that he is working hard to overcome the and is making steady progress.There are times even last year where his game sense wasn't quite there. His skills aren't as slick as Macdonald or Mackenzie. Despite his height he doesn't really create a threat arially and can't play forward well. Which is something Hustwaite showed glimpses of doing in his first game.
But please don't take it the wrong way as a knock on him, he's been great recently. When I say limited I mean it in the same way i'd say Brad Sewell or Liam Sheils was a limited player. Sewell didn't have the damaging disposal or slickness like Lewis and Mitchell. Sheils was good defensively but when he moved up the rungs as a key cog in the midfield he was never the type to be regularly in the votes. Or even how O'meara was a limited player.
Some of our young players at this stage look like they can be stars of the comp, some might be, some might just be role players and some may not make it. But thats the exciting journey we are on. Nash and worpel absolutely could be multi premiership players for us, but they could also be passed up and take a lesser role.
His strengths are the cleanest and hardest tackle in the game (he almost never concedes a free on the tackle), super-quick hands, a great tank and tricks.
He stilll has upside and he also has genuine leadership potential.
Put together, that is a serious package.
