Sorry, I hadn't read your post. Mine was just a general post and not aimed at anyone here in particular. I also didn't say anyone should keep their place unreservedly, in fact, evoke and tweak. Six changes from a playing XI is a bit extreme though, isn't it?
I would say invest a bit more time in most of them. Trott is obviously going to make way, but I would argue Jordan, Ali, Broad need a little more time, for varying reasons. I'm not sure why Ali was called up after being injured, so I'd say it's fair to think he might not have been 100%. More overs in international cricket can only help when he's not a frontline spinner for his club. Still something there.
Jordan is no better or worse than the others in the squad. Like Hoggard, he needs time to acclimatise, then assume the mantle when Anderson retires. Could go either way.
