England has an opportunity to make the best of their amazing talent pool and realigning their teams. Root needs to step down from captaincy. Cook should retire. New bowlers should be brought in. Yes, it will create a lot of noise but it needs to happen in the run-up to the world cup and Test championship next year.
It does seem like Root is not doing as well since being Captain - but they showed stats that Root averages 2-3 runs more as Captain than before! So I guess the jury is out with that one - I would prefer to see how he does in 2018 and then make an opinion.
Cook retire? As there is nobody to replace him at the moment, I am sure that i am not alone when i say that that i still think Cook has more runs in him on top of almost 12000 he already has!
Stokes coming in should improve the balance of the team!
Bowlers? Anderson has bowled well in these Ashes so far - he has a lot of skill and nice to see him performing pretty well in Aus (he hasn't always done so!) And as you can't deny his home record is very good, i reckon he deserves to retire gracefully and in his own time, which is likely to be in the next year or two barring injuries!
Broad? That is a different matter really. With the exception of the burrent test, his bowling in Aus in this Ashes series has been pretty poor. His bowling is a worry! If I would Coach, I would keep an eye on him over the next couple of series!
Apart from Broad, i would also have a worry about Woakes and Ali! They have performed well up until this Ashes series. But they are both a worry as they seem to be off form with both bat and ball. But they have both performed well in the past, so not worth making any rash decisions!!!
About the rest - Stoneman and Malan have been impressive so far! And Vince has shown enough ability to give him a longer run.
Other minor positives have been that our new bowlers haven't looked out of their depth.
The only thing left to see is how Crane fits in and bowls. Unsure if they will play him this series to be honest.
