The Waratahs have produced a groundhog season of performances, for just four wins, and it was the same again in a 40-27 loss to the Jaguares on Saturday night.
“I think from the top down, we’re very happy with what’s going on there,” said Mumm.
“A lot of the onus comes back to the players.”
Mumm said players had to bear a great deal of responsibility for their dismal year.
“Losing seasons are not easy and you can try and put fingers on things every which way and ultimately the accountability will come back to us,” he explained.
“It’’s a hard thing to do often and again on Monday you take a look, take accountability for what you did and what you didn’t do and move on from there.”
Next week’s game in Perth will be Mumm’s second farewell, having already done his series of ‘lasts’ in 2012 before a stint overseas with Exeter.
That first final game was a 32-16 final round loss to Queensland, that put the Reds on top of the Australian conference and into the 2012 finals, in the Waratahs’ most recent four-win year.
This time around, though there is more finality, there is less sentimentality for Mumm.
“Feels like I’m sneaking a little bit of cake that I shouldn’t probably have got,” he said.
“It’s always been exciting for me, another real honour to wear the Waratah jumper one more time.”
Mumm is treating this week as his last professional game, not hopeful, or anxious about whether he’ll have another opportunity at Test level.
“I thought there was a number of people that played pretty well in the June Series,” he added.
