As someone just reading through, you are arguing against valid points, and not convincingly.
in response to: You say Jonny's decision to pass the responsibility of marking Ulloa onto Rafael, in case he may be able to cut out a cross
Which is where he failed. Rojo and Blackett "covering the man with the ball, Jonny not recognising that he should be marking the centre forward (CB lesson 101)
Wrong
As I said, if Tyler has taken a look, he sees no immediate danger coming from midfield. His choice is to make up 3 men marking one in the box, or cover his fullback. He makes the right choice. Even then, by your standards for Jonny, he is in a position to cut out a cross, if he is fortunate enough for Vardy to hit it straight to him.
Rafael has the least blame in all of this, and this illustrates the first part of my post. You are willing to stretch opportioning the blame ridiculously, in an effort to exhonorate Evans.
You have an agenda, just as much as those who are slaughtering Evans, when it is a case of form being a good player's problem, and not "Evans is shit!"
You would be better arguing that, than trying to make excuses for an isolated incident, for which he is receiving warranted flack.
