Runs wise he is miles ahead. Now resigned from captaincy, I believe he will score at much faster rates than rest two. Smith has lost his form after Marnus debut and his own ban in 2018. He is not anymore. 2015-2018, he didn't face any problems in batting. Now he has started. Kohli, I don't know what happened. He is finding different ways to get out. One more year of lean patch and he will be thrown out of team from atleast one format. He is not going to achieve 15000 test runs mark which I thought he will achieve in 2025. But that's not going to happen. Root can crack that. Root won't play ODI cricket after 2023. So just test cricket which will help even further to post runs in test cricket.
Rutherford is not in form and Bracewell newbie in test cricket. And Conway and young are also out of form. I hope Nicholls is recovered. I want to see New Zealand Winning and Harry Brooks getting chance instead of Bairstow.
