What about Jock Stein, a non catholic, who nonetheless made all his catholic players attend mass on Holidays of Obligation, if Celtic were away on European business.
Very arrogant and presumptuous of him.
Was a different time. He rightly would not get away with such nonsense these days.
How is it arrogant if someone is a Catholic?
Isn't Sports Psychology being even more presumptive and getting away with it these days?
Ok Joe, its NOT arrogant and presumptuous to force someone else to go to mass.
Christ lad, you'd argue black is white just for the craic! 
Whatever sports psychology (whether its Jim McGuinness or Enda McNulty or Eileen Drury or whatever) is or isn't is irrelevant to the fact that forcing a subordinate to attend a religious ceremony is inappropriate.
Why is it any more inappropriate than a sports psychology session? How is the comparison irrelevant?
If they were Catholic its entirely appropriate as he probably feels it would get them in the right place for performance.
Didn't say it was more or less inappropriate.
I said whatever the rights and wrongs of sports psychology, forcing people over whom you hold power to partake in religious ceremonies, just because they were raised catholic, is absolutely inappropriate and unjustifiable, especially in this day and age. You're arrogantly presuming that you know what is best, from a religious perspective, for an individual.
It may well be the case also for the use of sports psychology. Or it may not (I don't know enough about the field). I would hope that a player would be free to opt out of such sessions if they did not find them useful. And I would hope that any player would be free to tell Mickey Harte where to stick his rosary without fear of penalty or other repercussion.
Your moving the goalposts to fit your antirelgious bias
Tony said it was the Catholic players not "raised Catholic" so our discussion is based on that.
If a player adheres to a believe system its entirely appropriate for the manager to ask them to fulful it as well as he can.
Doing so would more likely have a player who's head is in the right place, more likely to get maximum performance for the player and more likely to get maximum performance for the team. It a save assumption not an arrogant one, whats different now than the 60s?
Sports Psychology would be considered the same as any other preparation technique whether that be diet, S&C or team training, if you decided you arent gonna do it cos you dont believe it would be any use you would end up like me when I was a minor out on your hole.
There's not a manger in the country would stand for 2nd guessing his techniques on training psychology, team building, routines or anything else, sometimes players have to sacrifice part of themselves as individuals for the good of the team.
As for telling Mickey Harte to stick his rosary up his hole without recriminations catch yourself on FFS, any insult like that carrys consequences. Look at Kevin Cassidy / JMG incident, Cassidy did less than insult the manager and I thought JMG was wrong but you couldn't argue with the end result.
