Kilmarnock have had a great season but this was a game that went too far against a side who came here with a desire to score goals.
Before kick-off, Rodgers described the season as „very challenging“ and „a bit boring“. Not vintage, said the Celtic manager.
He may have had his previous visits to Rugby Park in mind when he said that, but no wonder. It has been an uncomfortable place for Celtic this season. Derek McInnes is one of Bogie's rival managers.
What unfolded in the first half was the exact opposite of what had happened before.
The sights and sounds of Rugby Park were also a contrast. Celtic were completely in tune with the flow, scoring high-class goals as requested by their manager and accelerating past the victory line, making it easy on the eyes.
The ugly flip side was the gruesome elements that were being shouted among the visiting supporters. An attack on the ears, a disgusting noise.
This celebration went on for years, perhaps reflecting how draining this season has been for Celtic and how punishing this title win has been in many ways.
Rodgers' use of the word „boring“ in his foreword is interesting, as it speaks to how deeply the Celtic manager had to work to get his players over the line.
They are there now and have a big day to cap it all off on Saturday when they face St Mirren at home.
Almost everyone doubted them at some point this season – even a section of their own support staff.
Perhaps they too doubted themselves at different times, but they showed steel when needed and class at Kilmarnock.
The hardships of a league season sealed with glittering glory.
