If Rangers win the SPL or the Scottish Cup by the end of 2020, I'll issue a grovelling, personalised apology to each and every Ted on P&B that requests one.
On a scale of probability, I'd say that Hibs winning the Scottish Cup or Not-Celtic winning the league are considerably more likely, largely because most Not-Celtic teams aren't absolute financial and sporting train wrecks in the way that Rangers currently are.
They COULD, but if they did, they'd have to have cheated, wouldn't they, and we all know they're above that kind of behaviour.
