Yeah, when you consider further Rojo is a more natural LB (I personally think you'd be making an even bigger mistake trying to play Blind there), and folk are putting a heck of a lot on Smalling's form the second half of last year as opposed to the very average career he's had to that point; and it would be real surprising if all your eggs on one of the most vulnerable areas of the team have either been put on Ramos; or the theory that better protection in front of the back 4 will lesson the problems behind.
I do like the look of McNair though going forward. Be interesting to see how he continues to develop and just how much time on the pitch he gets this year. And Jones settled in a position now could still fulfil his early potential. But he needs that quality experience alongside him.
All that said there's still over a month of the window to go so a lot can change yet.
