Green has the potential to average in the mid 40s with the bat and early 30s with the ball, which would put him right up there, and his numbers at every level except test indicate he could do that. But he just hasn't been able to make the step up from FC. I'm not sure he has the powers of concentration (like most young players these days) to excel at in the test arena against bowlers that will consistently challenge you, he often seems to get out making a mistake.
Somewhat related, but I think younger generations these days are growing up in an environment (with the internet, social media and now AI) that does not foster practicing concentrating for long periods of time, in any field, sports or otherwise. Tiger Woods superpower was his ability to concentrate for very long periods without making a mistake, and the same ability is needed in tests. Modern test cricket is probably a little bit symptomatic of wider society; it's not random that a lot of test sides these days are full of over 30s with younger players preferring T20s which are more in line with the quick, short, instant gratification type of entertainment these days.
I'd be interested in stats on % of drawn tests each year as well, but I don't have time to look that up right now. It feels like there is a LOT less draws these days with batsmen scoring faster and getting themselves out a lot playing aggressively.
