In white ball cricket they do have ridiculous team, they can even field 2 different teams in limited overs but they seems doomed as far as test cricket is concern. Poor Root is doing all heavy lifting for them.
Well... I have to agree. England performs poorly in test cricket when compared to the limited overs variety. On the other hand, Australia is one level ahead, when it comes to the longer format. Their players always perform the best in test, and especially so during Ashes. While I feel that England is having the upper hand due to the recent form, they will be digging their own grave in case they ignore the challenge. And as you said, they are a bit overdependent on Joe Root, similar to the case when Australia depended on Smith during the previous series.
