Really not sure the 4 seamers was as big an issue as it's being made out to be. We could have 6 spinners if we wanted, the issue isn't the number of spinners, it's the fact that all of our spinners are, frankly, awful.
I'm still not a fan of Rashid, too inconsistent, seems like he's soft in the head as well as soon as there's a bit of pressure on him (turning pitch, batsmen attacking) he turns to mush. You can say that he's a leggie, so he's going to be inconsistent but that's nonsense, just look at Yasir Shah, Adam Zampa, Davendra Bishoo, even Ish Sodhi! They can all at least land an over vaguely where they want. Time to get shot of him I'm afraid, cant see that Mason Crane would be any worse. Can't see that Moeen can justify playing just as a bowler, and given his soft dismissals this series, I'm not sure he can hold down a place as a batsman either.
Tough times, but I think given Ben Stokes being the allrounder, and Chris Woakes certainly knows which end to hold, we can afford to pick whoever is the best spinner, regardless of their other abilities. Got to be Leach or Rayner really though? I reckon if either of them can string together a decent start to next season, they could well be in the frame for the summer tests.
