What I suspect is this. Most match-going supporters, and most football supporters, whether armchair or not, would have wanted the games to go ahead. Not because they absolutely have to get their ‘fix’ of football, but because a minute's scrupulously observed silence at every ground in the country, possibly followed by the singing of the National Anthem, would have been much more moving as a tribute than anything that's going to take place tomorrow. Football supporters understand this. And it would have been beamed to literally millions of viewers around the world.
However, I believe it would have been strongly disapproved of by those who are either indifferent to, or hate football. I know some, so do you. I don't think the powers at the EFL wanted to risk that disapproval. I think they're wrong, but hey, there you go.
