Based on me using my eyes.
You don't need to make any direct comparisons to know that the standard is poor. Its the very basics we're talking about too.
David Marshall kicked the ball straight to a St Johnstone player yesterday so they took the kicking duties off him only for his centre half to pass the ball straight to the opposition which led to a goal. That sort of thing is endemic in our game.
We have players who consistently pass the ball straight out of play under no pressure whatsoever.
We can just say ach well that's the way it is or we can demand better. If you want the game to improve then there has to be at least an appetite for it from fans.
Everyone else being equally as shite (which I don't accept at all) has nowt to to with it.
