Yes but Moeen has played against that before with the Aussies, dealt with the pressure, and it isn't going to potentially affect his long term confidence. That isn't to say if we get into a good position then Rehan can't then come in so under less pressure. I suspect he'll end up sharing the spin bowling with Root. Moeen also, in theory, strengthens the batting line up.
What this situation does show that we have so little depth in the spin dept. English cricket really needs to look at this but whether the ECB can pull themselves away for the rubbish that is 'The Hundred' I doubt.
He has experienced the pressure.....it's a bit of an open question about whether he's dealt with it.
11 Ashes Tests (17 innings); 20 wickets at 64.65; economy rate almost 4; strike rate over 100.
It's a pretty horrific record - and by the way, that is substantially worse than Joe Root's Ashes record, which is 17 wickets at 41.23; economy rate 3.68; strike rate 67.
And now we plan to throw him back in after two years of playing nothing but white ball cricket? I think the Aussies will target Moeen every bit as much as they would target Rehan. And Rehan has much more talent to potentially deal with it. Does he have the temperament? We're not going to find out unless we give him a chance.
And if England are too timid to give Rehan a shot.....I might be inclined to play four quicks of varying styles, and have Root spend a lot of time over the next two weeks bowling in the nets!
