For the record, I'm not actually an England fan (check the userbar) I just have an interest at all times in seeing cricket being played as well as it can be.
As for your point about depth of talent, that's all well and good when it's being selected, but one of probably the three best batsmen in the country isn't even in the Test squad - though he did at least get a gig in the Perth game. That man is Liam Livingstone.
And that's without going on to the bowling stocks. Bowling talent has been mismanaged in England since I was very young, and I know that at least partly from having been a bowler mismanaged in England. To illustrate my point, two of the bowlers used in this Ashes series are
Jake Ball and
Craig Overton; now if you can spot any differences in their bowling (besides Overton being marginally more accurate) then you've got a better eye than I have.
For me, the Ball and Overton situation points to mismanagement on two levels: firstly, they're both in the side ahead of Tom Curran. Now, I'm not saying that he's going to single-handedly win the Ashes for you, but his ability to bowl a ball that comes back into the batsman, coupled with his skiddy trajectory, mean that he offers something none of the other right arm fast-medium bowlers in the England side do. The second level is a more personal one: Craig Overton is a 6' 5" seamer who bowls at roughly 82 mph, and doesn't move the ball much. Now, I'm 6' 5" tall, and at seventeen years of age could touch 80 mph if I really put my back into it. I also used to hoop the ball around corners. Now I'm not saying that I should have made it to where Craig Overton is today - I didn't want it enough - I'm just saying that it's alarming that nobody really made an effort to work with the obvious potential I had.
