Dean's demeanour stayed intact even with the midweek O'Connor and Beale shenanigans before the Wallabies edged home by a point in an error-filled test.
There was no excuse needed from the Wallabies, they won the test, they could now win the series, and with that, perhaps Deans could make a plea for this job.
The demerit points had risen - performance, style, player behaviour, sponsors' feedback, supporters' uncertainty - but the Wallabies could win the series and perhaps offer Deans another podium to argue for his retention.
Strangely Deans, after declaring George Smith was unfit for the second test, included him a few days later for the decider. Good decision but unluckily for Deans on a night when his team also lost Israel Folau, Smith was ko'd early.
So was the scrum and when the Wallabies' finger in the dyke approach wilted late, they were drowned by the Lions.
Deans was sluiced out too into the muddied ARU waters. His troubled look and comments about the uncertainty of international rugby coaching and decisions to be made by others, hinted at an assessment about his future.
As he had done for chunks of his work with the Wallabies especially with their repeated inability to share results with the All Blacks, Deans stayed calm if a little detached.
He or someone attached to his mouth, answered the inquiries in an impassive tone.
Deans did not give much away, there was little emotional connection to the public.
On Monday he and ARU boss Bill Pulver negotiated an exit, did the $400,000 early severance deal, and Deans rode off into the sunset with his senses tuned for his next contract.
