Maybe but that doesn't make your criticism of Jones any less over the top.
The Jones/Smalling thing is one of those standard redcafe splits, with two camps on either side of the split. If/when one of them has a bad game (or makes a mistake) they get it in the neck from people who think their favourite has been harshly treated in the past. Which is what I suspect you're doing here. If Smalling had put in an identical peformance to Jones I think the general rating would be that he had an average game but could do better. Along with a few Jones fans saying he was diabolical.
I don't think it's that clear cut.
Jones has been playing very well this season and I've always said that I hope it continues because it's been needed for us as a club defensively, but also him because I quite like him.
However yesterday he played quite a few levels below the average he's been playing this season. He was shaky, and unnerving at times luckily Liverpool didn't pose much of a threat and often times when they did, Rojo was there to provide cover. I don't think that's over the top at all.
He did pass the ball to DDG far too often too, this is also a criticism that Smalling has faced recently, I personally don't mind a defender who would rather pass back to the keeper, especially since DDG is so comfortable with his feet. But since the game has evolved and ball-playing defenders are sought-after, this is another area where he wasn't as good as he has been this season. Again, I don't think that's over the top.
I didn't say it was a terrible performance, average seems about quite right. But we have 4 defenders competing for 2 spots therefore criticism is going to be more common.
