Not really the case. He was about 22 when Geoff bought the club. A fully grown adult that chose to support Rangers instead of Saints like his dad. I'm not surprised fans try to brush over this but it happened. He may have developed a soft spot for them over the years and does Chairmany things for games but he's stated a few times he can't wait to get out. It's probably family obligation that keeps him in post. He never whinges about the additional roles he's found time to take on at Hampden over the years in addition to McDiarmid, just Saints.
