Not every fan of a football team would die rather than do anything that didn't end up as the best for his/her team. Its the usual childish and myopic view on forums to assume that the minute you lay claim to being an Aberdeen fan that you should never take any other route in your future than to support/play for/manage/invest in your club.
Maybe he felt that there would be too much pressure on him to deliver at the team he supports, maybe he felt that the small investment he had to offer would do little for us, maybe he wants to be a big fish in a small pond, maybe he offered us something and was knocked back but doesn't want to upset the club by going public, maybe he believes that a club who are debt free is a better financial investment. Who knows, I still say good luck to the man whatever his thinking.
