I mean far be it for me to point out this correlation, but it's interesting that the two teams who are shouting the most were the ones who had massive benefits in comparison to the teams around them (fanbase, funding, stadium, squad sizes, the ability to sack managers mid season) yet still found themselves at the bottom of their league.
Could it be that they have just utterly failed and are now blaming all of Scotland for their failure? I'm sure less charitable people than I would say so.
