Dome stated in that excellent A Leagues article someone posted - the blossoming ot Rufer as one of 3 major factors for the Nix this season. The other Chief (Kiwi like in his behaviour) & a 3rd I can't remember.
But Dome made a definite point of mentioning Rufer, is a standout factor in this season's success. Know one knows the club better than David Dome, he's been there a long time.
So I'd say as well as the stuff we see on field, and in post match interviews (very impressive, calm,steely, measured, matter of fact - a real leader), Rufer is now a huge presence around the club in general.
I mean it helps when you are winning, but there is far less whining from the club now about refs, and other 'the world is against the Nix' type baggage. That stuff always bugged me. Merrick & Durante were bad with it. It's not a winning mentality. For sure the reffing has got better, and is no more Nix Out FA
shark going on etc. The club are yes a more valued part of the league.
But I reckon Rufer is a driver of a no excuses type mentality, that holds everyone to high standards, whilst also embracing the young guys coming in making them feel welcome and free to express themselves. Again winning helps alot in all that.
