Jones this summer hasn't batted poorly - the number of RUDs he got in The Ashes was quite remarkable. I do worry a little about this winter though, because I haven't a clue how good Jones is at starting his innings against quality spin because we've never really seen him do it.
However, Jones' keeping in the Australia Tests this summer wasn't up to standard - rather than being excellent, very good or even good, it was, simply, poor, and you can't keep a wicketkeeper like that for ever. I do believe, though, that Jones has what it takes to improve, and if Jack Russell keeps working with him he's in good hands. There doesn't seem to be any falseness in Jack's enthusiasm about Jones' wicketkeeping prowess (and Jack's very much against "giving the gloves to batters" as he puts it, as is Bob Taylor) and if Jack thinks he can become a good wicketkeeper that's good enough for me. And Jack certainly had a point when he mentioned that Jones' wicketkeeping was near enough faultless in the Bangladesh games and the ODIs. What's, perhaps, a little worrying, though, is that he seems to have been fine for short periods in the field and less good when it gets a bit longer.
As for Pietersen at The Oval - wasn't a chance to Gilchrist, he had precisely zero chance of catching it. Only way it would've been catchable is if he'd missed it completely and it'd gone straight to Hayden.
