It certainly does appear to be a.....volatile environment.
I would speculate- and that is the important term- that HBG reacted to what they thought was a slight against the financial backers of the club from decision makers at board level when certain financial decisions were not made in consultation with the HBG board. My speculation is that they reacted without all the information & that it came to their realisation that the issue lay...elsewhere...and once that element was removed from the club, and with the help of PVL & his interaction with BOTH sides- they saw fit to invite those board members back.
Does it show that the HBG board made a mistake? Yes, in that theory it does. Does it show they are incompetent? I'm not sold on that. At any level, there will be mistakes made by PEOPLE. The actions of those people after the mistake often dictate if a person are incompetent or not. If they saw they made an error & then offered to rectify it by asking the board members back- I won't hang them, or anyone, for that.
