But why does this even need to be a topic of discussion?
Putting jibes between supporters to one side, does the savagery from pundits and media come from a place of snobbery?
There have been suggestions the optics of the tactics board weren’t great, but if Celtic had won then those very suggestions would be non-existent.
They didn’t win, of course, but why shouldn’t a manager use the tools they feel benefit them?
Then you can factor in that Nancy had just a handful of hours on the training pitch with his team before Sunday.
Former Rangers coach McCann said himself that players often prefer to see tactical information visualised.
Ever wondered what coaches are looking at on the iPad propped up in the dugout? Shock to the system here, but they’re not ordering a takeaway or catching up with their new favourite series.
Sure, fans want positive first impressions from their manager, and perhaps some of the Celtic support had toes curling when they saw Nancy’s mini tactics board while their side were 2-0 down at home.
That can be true while also recognising that the fallout has been extreme.
“I think the reaction really has been over the top,” says Celtic fan podcaster Paul John Dykes. “You’ve got the visual element – let’s get the message across quickly.
“After the second tactical switch, we create five chances. If we pull the two-goal deficit back, he’s a genius and the tactics board’s genius.”
