Just after half-time, with his side trailing 20-7, Daryl Gibson summed it up beautifully: "It's who's going to blink first."
The Rebels then conceded eight straight penalties to all but self-combust and throw away a 13-point lead and suffer their 14th loss from 16 starts against a Waratahs team with a clear psychological advantage over a Melbourne side that left the SCG shattered.
Captain Michael Hooper was outstanding in his 100th game for the Waratahs, who are now four points behind the Rebels in the Australian conference.
