Yeah, but you are guessing either way. Plus here I think the immediate reaction of most people was red, it is only the multiple replays from several angles that call it into any question. Whether it was a guess or not, Taylor had to make a decision and I personally think he made the right one. Also questions the theory that referees don't make a decision and reply on VAR, but that is a different debate.
I watched it in a pub in Spain in the middle of Newcastle and Villa fans and the conclusion of everyone was that he would be walking. I said it straight away, but by the time the first replay had ended the Geordies were screaming off and the Villa fans had their heads in their hands.
