Let's start with Oldham. It is close to impossible to regulate against incompetence. That is the problem there.
Nobody is crooked, nobody is corrupt, integrity as always will be in the eye of the beholder. The malaise at Oldham is that of stupidity, foolishness and poor practice. That is not the same as malpractice. Football clubs have got to be allowed to fail, too. That is how movement occurs.
Oldham were founder members of the Premier League, blew it and have ended up contemplating fixtures with Boreham Wood and Eastleigh next season. Brighton, Fulham, Burnley, Huddersfield and Bournemouth were all in tier three in 1992-93 and may be in the Premier League next season.
