You are right he should have been punted straight after that game but I guess Milne and co already made the mistake of giving him a new contract a few months before that.
They gave him another season to make amends and we ended up getting knocked out of the Scottish cup by Dunfermline at home which wasn't much better.
I think the following season under McGhee we got knocked out the cup by Raith at home after a reply too, thats 3 years in a row we got knocked out of the Scottish cup by lower league opposition, mind you it was harder in them days to win the Scottish cup
