Aye, total meltdown from Rangers that day. Their goal difference compared to Aberdeen's meant that even if they lost by 1, Aberdeen would have to beat them to win the league. When we went a goal up, instead of keeping things tight, Rangers piled everyone forward and we scored a second on the break. So, Rangers piled everyone forward again, and we scored on the break again.
That result meant their goal difference was now worse than Aberdeen's, so the Dons only needed a draw to win the title. Unfortunately, they blew it.
