Here's an amateur's analysis of the coup rumours.
If we're to use IBBs playbook on coups, using the Shagari coup as a case study, and also consider the Jan 1966 coup, then it might be too late.

The fact that there's a serious public discourse among citizens considering if a coup would be welcomed as an answer to the politicians, due to what looks like a phantom coup plot, simply points to what IBB described as "coup baiting."

It means there's a real group of officers and political backers who want to guage the reactions of the public to a real coup.
