I agree, everyone has their own view on individual players and their contribution to the Club. Doolan has been rewarded by a coaching position, the first choice "striker" position has been his largely due to the lack of competent competition. Erskine has always struck me as being more vocal than Doolan and no doubt would no doubt let his views be known within the Club. This may not go down too well with the management team.
Every player has a shelf life, we have to accept that things change. The only hope is that the current changes are for the better. It would be nice to have the luxury of keeping guys on for sentimental reasons and the occasional "cameo performance", but things have to change pretty quickly.
I do not know how the new signings will do, but no one can be happy with the last eighteen months. Lets hope for improvement.
