Irrespective of whether one is a supporter or otherwise of the coaching/selection abilities of Steve Macnamara, I would be very concerned if I was his employer, for the reason that he seems not to be in control or have the backing of the staff under his jurisdiction.
There are some basics for all walks of life whether in business or sport.
For my sins I was the MD of a company not large, but still had some 50 employees and my strength was in the capabilities of my management team, for the reason we have different individuals a manager has to be all things to all of his staff, a mother, a cajoler, a mentor, a coach etc. etc. by adopting these simple policies he/she will gain the respect of their charges.
Having acquired that respect people will listen to the manager, abide by their rules and regulations and give him/her their all. SM seems to have failed in this department else the players involved (members of the Hockgate team) would have stood by his instructions in the first place, and we would not now be ruing the absence of the players involved.
