the year jack won the coleman the game plan was to isolate jack one out as often possible. This played to his strenghts, reading the flight of the ball, a good leap, and very good when the ball hit the deck. he was able to do this , more often than not, without the hindrance of extra backmen scragging and blocking him.
Hardwick said, and rightly so, that we had to get other avenues to goal besides jack, so the have tried to create a multi pronged forward line.
This has not been sucessfull for a number of reasons, some of which are down to jack, and some which are beyond his control.
But he needs to rectify those which are within his controll. The problem, besides his attitude, is that IMO, he has never been a lead up type forward. seriously, how often has jacke taken a mark, arms outstretched, on the lead, even in his coleman winning year?
Unless he can add this string to his bow, he will only cut the mustard with another quality, bustling type forward along side him in the forward line.
he is not suited to being the sole key target, under the current game plan, but you select your players to the game plan, not revolve a game plan around one player. It may have worked for north with carey, but he was something special.
