A significant stat that Bairstow averages 53 when England bat first in tests, and only 29 when they bat second. This highlights how much the physical strain of keeping affects the potential of his batting. Additionally he was averaging above 40 at 6/7 whereas he has averaged 28 when batting in the middle order. It's too much of an ask in my opinion. He should bat 6/7 if he still wicket keeps, or he should stay in the middle order and hand the gloves to Buttler, which would probably be my preferred choice.
A key thing to note from South Africa's tour of Sri Lanka, is that England will need more than 1 frontline spinner. Maharaj bowled exceptionally well in the sc but the seam attack was uneffective. By the end of the test series, Makram and Elgar ended up bowling a fair number of overs. Iirc, Sri Lanka had 3 main spinners, which meant that the trial by spin was unending. Albeit the problem for us will be having the quality of spin bowlers that can expose the theoretically helpful conditions. Likewise it is important not to put too much emphasis on spin. Anderson and the variety of Curran could play a much more pivatol role than spin bowling that just isn't very good.
At the very least, I would like to see Leach and Ali be England's two frontline spinners. Rashid is capable of the magic ball, but he always bowls a bad ball in an over and relieves the pressure. It's okay in odi cricket where the batters are always trying to score runs and are more likely to misplay, but test match bowling relies on the culmination of pressure. Continuous testing balls.If the batsmen is always assured of a bad ball an over they will find negotiaitng the rest of the over much easier because they never have to force the issue.
At this moment, my team would look like this:
Burns
Gubbins
Vince
Root
Bairstow
Stokes
Buttler (wk)
Ali
Curran
Leach
Anderson
