Instead, he too, was left with an uncertain future with three round-robin matches remaining, including crucial derby games against the Chiefs and Hurricanes, and the prospect of the playoffs to come.
The Crusaders' review will come to several reasons about why the team failed to kick on following the international break, and the efforts the eight All Blacks in the team, including new skipper Kieran Read, exerted in the three tests against Wales will probably be one conclusion.
Their failure to respond to pressure in their defeats to the Chiefs, Hurricanes, and Lions in last weekend's quarter-final defeat in Johannesburg has been identified by Blackadder as a major reason for their fall. In the past the Crusaders' resilience has been a strength.
But the fall-out from the Matson/Robertson decision must be a factor too. It is understood that several senior players within the Crusaders were upset by the way Matson was treated, and few of them played to their potential in their team's three defeats this month.
True team unity - the sort teams such as the Chiefs and Highlanders show week-in, week-out on the pitch, takes hard work and can go in an instant.
Blackadder made a point of saying his team was more unified than ever this season before the June break, although a winning team is a happy team. Afterwards, romp over the hopeless Rebels aside, there was little sign of it.
The tough questions need to be asked in a franchise which hasn't won a title since 2008. At the very least, maybe the Crusaders should have waited until the season finished to announce Blackadder's successor.
