In all the noise and fallout after Sunday, it's easy to forget the actual football.
Everything that followed the final whistle has taken centre stage and the debate around it will rumble on for some time.
But buried inside what might be the biggest smash and grab at Ibrox in years were a couple of performances that deserve far more credit than they've been getting.
Two players in particular stood tall for Celtic on a day that demanded character as much as quality. Auston Trusty and Liam Scales.
They're not always the first names supporters rush to praise. In fact, both have taken their fair share of criticism in a Celtic shirt. But on Sunday they delivered the kind of performance that reminds you why mentality matters in games like this.
For 120 minutes they put their bodies on the line. Blocks, headers and clearances – again and again they stood firm as Celtic dug in. When the pressure was at its highest and the team were hanging on, those two were right in the thick of it.
Then came the penalties. With the shootout level at 1-1 after James Tavernier's early miss, up stepped Trusty. And if you're telling me you weren't on the edge of your seat when the big American walked forward, I'm not sure I believe you.
But those fears were completely misplaced. Trusty looked the calmest man in the stadium, coolly sending Jack Butland the wrong way before rolling the ball into the opposite corner.
From that moment the momentum was with Celtic. Reo Hatate and Tomas Cvancara did the rest, while Djeidi Gassama's miss sealed the outcome.
And one key detail that emerged afterwards says plenty about the mindset of Trusty's defensive partner, Scales.
As captain for the day, the Irishman was lined up to take Celtic's fifth penalty if it had been required. A centre-back, playing left-back on the day, who has never taken a penalty in his professional career – yet willing to step forward in one of Celtic's biggest moments in years.
Whatever you think of him technically, that says everything about his character. Having two defenders among the first five takers shows just how ready both Trusty and Scales were to shoulder responsibility when it mattered most.
Scales captained Celtic on a day that will live long in the memory, later describing it as one of his proudest moments in the shirt. It's easy to see why.
Now the focus turns to finishing the job in the weeks ahead – both in the Scottish Cup and the Premiership.
But whatever happens next, one thing after Sunday is beyond doubt. The character of this Celtic side under Martin O'Neill, and of leaders like Trusty and Scales, is unquestionable.
