Until this week, Early Doors thought the Rooney Rule was the law of economics that dictated a packet of cigarettes was worth £200. However, it turns out it is actually a proposition that could transform the fate of black managers in England.
Named after Dan Rooney, the owner of the Pittsburgh Steelers, and introduced in 2003, the Rooney Rule is in effect in the NFL and dictates that when interviewing for a vacant coach position, a team must speak to at least one black candidate.
Civil rights lawyer Cyrus Mehri drafted the law and, invited by PFA chief executive Gordon Taylor, he met with the organisation, the League Managers' Association, the Football Association, the Football League and the Premier League prior to England's 1-0 win over Wales on Wednesday.
The PFA has now committed itself to exploring the measure. As Taylor explains: "In football terms, we are the most cosmopolitan country in the world. There is no distinction between colour, creed, nationality or background.
"However, the PFA spends a lot of money training players for the future and understandably, one of the most obvious areas of interest is coaching and management. For some reason the number of black people who actually get a chance in this area is very small.
"We are committed to this issue and Cyrus's experiences can offer us an insight and some solutions that can begin to address a concern that will not go away on its own.
"Twenty years ago, Cyrille Regis and Luther Blissett did not try to carve out a career in management because they did not feel they would get a proper chance. In 2011, it is in no one's interests for potential managers to be put off for similar reasons. We will not be taking this off our agenda."
Though speculation about the possible introduction of the Rooney Rule to English football has predictably led to claims of positive discrimination in some quarters, it should be emphasised that teams would be under no compulsion to hire black candidates, merely to include them in the interview process.
At the very least the introduction of the rule would ensure valuable interview experience for a group of potential managers who at present remain woefully underrepresented.
Taylor is right when he says: "All we are asking for is an interview. But the more times people attend interviews, the greater the likelihood of them eventually getting a job.
"This has to be a good thing because it broadens panel of potential managers and coaches clubs are selecting from and opens up the possibility of greater experience. That should be what every club is looking for anyway."
Certainly, action does need to be taken to address the chronic lack of black managers being given chances in the Football League and the Premier League. At present, the only two in work at the 92 league clubs are Chris Hughton at Birmingham City and Chris Powell at Charlton Athletic.
Idly flicking on to Sky Sports News on Wednesday hoping for a glimpse of Natalie Sawyer, ED was assailed by some quite eye-opening statistics.
Since 1992, only 33 of 1,100 managerial appointments have gone to black managers. Indeed, since 1965 just 35 jobs have been filled by black candidates. The Premier League - a proud bastion of diversity with its players from all corners of the globe - has only had five: Ruud Gullit (at Chelsea and Newcastle), Jean Tigana, Paul Ince and Hughton. The Championship has had five, League One has had 10 and League Two has had 15.
Contrast that with the NFL, where seven of 32 coaches are now black thanks to the impact made by the Rooney Rule.
Of course, implementing such legislation would not be without its pitfalls, and Mehri told the Daily Mirror this week that he encountered issues when doing so in the NFL, but that the benefits outweighed any initial reservations.
"There were some problems at first," Mehri said. "The Dallas Cowboys owner Jerry Jones thought it was okay to interview the black candidate over the phone and all the white candidates face to face.
"If there is passive racism present somewhere, we have found it erodes during the interview process. Sometimes, people are surprised with the calibre of a man when they meet him face to face.
"We are not saying clubs have to hire minority candidates. We are just saying 'give them a chance, maybe you don't know what you're missing'."
The current climate will change naturally with time, and perhaps an increasing number of black managers will be given chances at league clubs.
However, introducing a rule which offers more black candidates the opportunity to get a foot in the door where previously they had none is surely worth exploring.

QUOTE OF THE DAY: ""People can talk about my age as much as they like but there's nothing better than proving people wrong. I understand at 38-40 I won't be playing for England. But I'd much rather think I gave everything to play while I could, rather than thinking I ducked out too soon. When I was 25-26 I had a World Cup that didn't go well. I wasn't told I was old then - I was just told I was crap!" - Frank Lampard, 33, remains adamant he will be providing midfield mediocrity for some time yet in an England shirt.
FOREIGN VIEW: "There were ten players who didn't play. He is an important player, but the people selected for the national team are those who do well for their clubs, not the other way round." - Fernando Torres is put firmly in his place by Spain coach Vicente del Bosque after he was dropped for the 6-0 hammering over Liechtenstein that saw the country confirm their place at the Euro 2012 finals next summer. Torres has scored only once in 12 months for the best international team on the planet and saw replacement Alvaro Negredo bag two on Tuesday.
