To think about Kirke another way, he'll probably go down in history as the best ever career squad player. He's achieved more winners medals than the likes of Mike Bennett (Saints), Ricky Bibey etc, and he's outlasted the likes of Chris Feather, Simon Worrall, Liam Botham, Wayne MacDonald etc in this golden period of Leeds history.
It's a shame he does not seem to impose himself on the game as much as he used to - remember his heroic efforts chasing down wingers in the past? I suspect the low work rate on attack comes down to tactical reasons - Leeds have limited possession and we want our most dangerous players to have the ball in hand more often. Kirke offers more safety than someone like Achurch in this respect. He's played in countless big games before, knows the players and structures, and won't let us down on the whole. His selection is more of an indictment of the contributions of the likes of Achurch, Ward and Clarkson so far this season IMO, who have all failed to cement regular spots in the first 17.
