Although I agree with the majority in that Bell or Ballance are the most likely candidates for the chop, can England really afford to start changing the team just before an Ashes series?
After the Pietersen saga and the change of management, the ECB are probably trying to regain some for some stability and get hold of the organisation before they drop to the bottom of the Test rankings.
Personally I believe the selectors need to once again look at their bowling and "bowling" attack. By this I mean they need to decide on their 3 man pace attack (Anderson, Broad and Wood) their all rounder (Stokes) and a proper spinner. Otherwise, we will be sticking with this "bowling" attack where at no point does it look like we will pick up a wicket.
Sorry to say, but we are no longer in a position where we can chuck in a part time spinner (Ali/Root). I believe cricket has moved on from batsmen who can bowl a bit at international level. Unfortunately, if you want a decent bowler, a spinner in particular, you have to accept that they will not be getting many runs.
I say all this with caution however, as there is absolutely no one in a position to be called up to the team, Rashid probably being the closest to selection, but would you really want to blood in a new player against a settled Australia team.
