Gooch got booted after the last ashes tour and the bust up with KP....he was someone who knew how to bat in test matches, ramps is a superb technical batsman so must be able able to help with that side of it, but his test record everyone knows was poor.
Bowling wise Bond has gone back I think and Silverwood don't start till 2018. Interesting for me anyway reports Anderson and the bowling coaches had a bust up at Adelaide because England did not bowl the right length, Anderson seemed to pin some of he blame on coaching advice. Well I sorry but with that many test wickets you should know what length to bowl.
I think you are barking up the wrong tree looking at coaching.
I would be looking at the captain, and asking whether we have hampered our best batsman.
Seriously.i wasn't convinced last year Root should be captain and I'm not convinced now.
Is it more important to the team Root Is captain or get big big scores like smith, kholi,Williamson etc.
Because Root is right up there in that category....not as good as those 3 but not far off.
