1) A good point, you ‘don’t know’ so have assumed the worst.
2) He wasn’t ‘personally’ responsible, he was part of a committee that made a recommendation to others, including the then Chairman. The appointment didn’t work.
I’d counter that by saying the appointments of, for example, Ross Wilson and James Bisgrove appear to have been good ones. Graeme Park was heavily involved in both.
People don’t like to remember the good things/facts.
Graeme Park was and always being know as the guy who appointed Pedro despite have absolutely no power to do so. I believe he was one of many that quickly sussed that Mark Allen was a bad fit too.
