Sorry, Wow, I think you might want to pay more attention - the team (and backroom staff) have changed a lot. Apart from Cook, Broad, Anderson, I don't think any of 'em were playing in the all-conquering team that won the 2010-11 Ashes in Australia and were number 1 in the world. Wait, Steven Finn as well, though he was hardly an integral part of the team, Tremlett being the fast bowler.
So the entire middle order, the second opener, the wicketkeeper, half the seam attack and the spinner, plus the coaching staff, are all different
In the meantime, there were a few retirements (including England's most successful spinner and Trott at number three, who hasn't really been replaced. Plus the entire coaching staff changing at least twice (I've probably lost count somewhere along the way), and the whole KP debacle. And Andrew Strauss scarpering to become a Tory MP or something. They still look like a work-in-progress apart from Cook and Root of the top order batsmen and a few others (Woakes has been brilliant this summer, and Finn had a good test), though at least they've finally found a suitably ginger Durham all-rounder replacement for Paul Collingwood, injuries permitting.
