Old order faces youthful challenge
All three are articulate, media savvy and thoughtfully opinionated in their musings on the game. They ally their football experience with an understanding of social trends and change, and a readiness to embrace these, whether it be in re-working youth systems, their managerial techniques, or their willingness to challenge a cosy media consensus.
Similarly, a new breed of supporter has been patiently working to ensure that the old order of Scottish football must accept change.
David Edgar of the Rangers Trust once told me that Light Blues fans had the "big man in the big hoose mentality" - that cringing Scottish readiness to accept what one's betters insist is good for you.
Along with his fellow Trust members, he must now be gratified to witness a much more bolshie side to the Rangers support, as the fans contemplate a buyout.
Presumably, they've concluded that they can make no worse a job of running the club than those who got it into the current mess.
But highly intelligent managers and highly qualified fans alike face some serious opposition. They are often too sharp and too clever by half according to those who currently run the game and whose power is threatened by those inclined to a more open, democratic and accountable approach.
For the three managers mentioned and others emerging of a similar ilk, the game's ruling bodies and, indeed, even some referees and members of the media, may see them as too much of a threat to the status quo and that marks them out as dangerous and unpredictable.
All three have been eloquent and vocal in defence of perceived wrongs against their clubs and, while those in authority bristle at criticism, in a healthy and mature democracy, a concept often alien to Scotland, it is a welcome and overdue development.
For organised fans groups, too, there is a danger. They threaten the power base of some who instinctively feel it is their birthright to run clubs or organisations like the Scottish FA, Scottish Premier League, or Scottish Football League as personal fiefdoms and who respond with arrogance and disdain to fresh and innovative thinking.
But the good news is that intelligence will win out.
In a world of modern communications, the truth shall indeed set you free if you are a manager or a supporter ready to challenge the established order.
Football fans now communicate instantaneously and, in a world of Twitter, email and You Tube, the football establishment is open to a scrutiny never before endured.
Information is shared in an instant around the football community and there is no hiding place for duplicity.
The old football order will fight to the death, but "the times they are a changin", as Bob Dylan said, and football will have to change with them.
