I think the thing people are forgetting is that you can't just chuck tons of youngsters into the team and expect them to perform to a top standard in a short space of time. Kieswetter is unreliable, Morgan out of form plus Bairstow and Buttler are still new to the team and finding their feet. You can't expect any of those players to steady the ship mid innings and lead England on towards a big total. Until our other batsmen start hitting major form, we NEED Bopara in the team to play the same role that Misbah plays for Pakistan.
The youngsters need to be playing around more senior players like Bopara 'til they find their feet, if you chuck in Taylor then you are going to have 3 inexperienced batsmen in one after the other, they will put pressure on each other and stop themselves from improving. After the T20 world cup when they all have more experience, then put Taylor in the team.
