I agree with you Jimbo. But I look at other teams and their squads often look the same. I think of Australia with Warner and Smith. India with KL Rahul and Rohit. Pakistan with Babar and Rizwan. Other teams around the world can often incorporate their T20 stars into the test side and remain successful.
England have Stokes, Buttler, Archer, Woakes, Malan from the T20s plus Root and Wood from the wider white ball squad, so it's not like they don't have cross format players.
I think it wouldn't hurt though to look at the red ball skillset of their squad and try to bring in a few more guys whose approach is more suited to facilitating the talent of Root, Stokes, Pope, etc.
A good analogy is looking at PSG with Neymar, Mbappe and Messi. Phenomenal, exciting players but their team isn't really set up to make the most of them and the rest of the side isn't best suited to facilitating their talents.
Hameed seems to be making his way back to the player we thought he could be but I'd like to see more nuggety players in the top 3. Maybe not guys who will average a huge amount or smash teams, but experienced heads who will grind out a 30/40 and set a platform.
Burns is a bizarre one because he either seems to get out for zip or make a significant contribution. Not sure Malan is the best option at 3, wouldn't object to them selecting a third opener or demoting Burns to 3 and bringing in someone else up top.
