I think what @JamesL means is that if you say something is DOGSO outside the penalty area, it has to be a red card. If you don’t think it’s a red card, it would be SPA. It’s more of a terminology matter.
PS- I had no idea you aren’t a referee…….
That's fair enough if that what he meant. And it's where I sit on it, as a fan I see more of a DOGSO resulting in a red card when a player has the ball at his feet facing towards goal around 18 to maybe 30 yards out and gets tripped/pushed by a defender and clearly being the last man. I can't see how an attacker who has no control of the ball and it's still bouncing away from the attacker can be denied an obvious goal scoring chance.
When I see the comparisons online, you can understand why people think there is an inconsistency but on another day we may of seen some consistency as another VAR may not of intervened in the Arsenal game.
