I have no doubt our list has improved nor that it a catastrophe would have to occur for him to be sacked before the 2016 end of contract .Unlike Frawley and TW Hardwick has taken a list that was a rabble and turned it into arguably the best list the club has had in the last 30 years. Not only that but his determination to stick to the plan he presented to the board before being hired had been a big part of bringing the new stability to the club. The playing list knows where it stands, the off field staff know what they need to do to address any areas of concern regarding the ongoing success of the list/club.
As for not winning a final in 4 years, that's a bit harsh given he has only had 1 chance to do so. I agree though if in 3 years time he still hasn't won a final despite plenty of opportunities then we can question whether he deserves to keep going. But right now IMO this was the best move the club could make as it removes any chance of off field distractions getting in the way of us making the 8 next year.
However out list improvement has predominately been on the back of mature age recruiting whom all are of similar age . Not unthinkable that there is only 3 players in the best 22 who have joined the club , since Dimmas arrival , as an 18 year old and all are mids .
No issue till the mature agers start to retire or who's form start to mirror the form they had at their previous club .
