Only Dundee United come close to Kilmarnock's record of goals conceded (10) and they have played a game more.
Pre-match, McCann spoke of his players having belief, of his side having a plan. But, as the old adage goes, everyone has a plan until they get punched in the face.
And Kilmarnock keep getting punched in the face, and early. In their past five games, they've conceded in the 16th minute or earlier on every occasion.
Here, it was after just 222 seconds. Short of four minutes.
That was after a change of shape, with McCann moving to three at the back in an attempt to shore up the defence.
At half-time, three changes were made and the formation reverted to four at the back. The experiment had failed.
In attack, they actually had a similar number of chances to St Mirren, and more shots on target, but Jacob Chapman only had one real save to make - a trundler from distance thanks to Michael Schjonning-Larsen.
They need a decent result, and quickly. Can they get it at Pittodrie on Saturday?
