Taylor had to clear a very high bar just to give the penalty.
First he had to give a type of decision that's almost never given, even though it would influence the outcome of the match.
Then he had to choose to give this almost unprecedented decision even though it was incorrect.
And to give this incorrect decision he either had to overrule the evidence of his own eyes or ignore the lack of it.
He's really outdone himself, it's a masterpiece. Frankly given the sheer effort and talent Taylor put into fucking this one up, the VAR probably would've felt rude to call the error "clear and obvious".
