Okay this is where I step in as a player. In post 16, it was stated that an attacker would expect this challenge. If I were to expect this challenge coming in from experience, I'd consider stopping football. I don't think it's anything to do with football. I've been hacked down a couple of times like this, and the only thing you're thinking when you're that far ahead of the defender is what you're going to do next (a shot or pass) , and the moment you get hacked down, that hurts as you DO NOT EXPECT THIS.
And I agree, last minute WC, I'd love him to make the tackle but you know it's got to be red. All the times this happened to me can be counted on one hand as it is lower level, but every time it was red and no one complained. I cannot state how much I disagree with that notion, its an incredibly dangerous tackle. I'm not even sure I'm discounting SFP even with the ball in playing range, it's not like it's an attempted trip, he just scythes him down.
A very specific example, which I think is similar to Shaw's tackle is this one, from 6:30 onwards
The player expected that red and I'd have no doubt Shaw would have walked off without any issues there. He knew damn well what he did.
