the captain and coach feel they need 6 bowlers to take wickets across 5 days play
See this is what I am concerned about. Didn't they have 6 bowlers in the last test - Anderson, Curran, Stokes, Rashid, Ali, Root. How many overs is the 5 and 6th bolwer expected to bowl, the primary 4 bowlers do their job? Isn't this the case of the mgmt getting the team wrong in the first game, where they screwed up picking Ali, Rashid and Curran. They should have picked 2 out of the 3 or if you are looking for a specialist spinner they should have picked Leach. It also does not help that Root has confidence issues with Rashid. I am not saying he is a great bowler but Morgan does a great job of managing Rashid in one days (different format). They have always known that Rashid is going to be more expensive and if they do not account for that when selecting the team, it's their fault.
Also, how is having 6 bowlers going to help with the batting issues, which got blown away for 77 runs. If the current thinking is correct the bowling unit will be Anderson, Broad, Stokes, Curran, two from (Ali, Leach, Rashid), Root, Denley.
I have no proof but is it possible that Baristow made a stink about not wanting to bat at 3 or his continued desire to keep and the England mgmt basically folded. If he is selected to keep he should not bat any higher than 7.
I used to admire Baristow's passion now I think he is a complete crybaby and just being selfish based on the last couple of instances both against India and Sri Lanka and not a team player.
