Thinking about it, you can see a couple of things...
1) the players being called for years to be included (particularly on this forum) have looked average at best... Isiekwe was average, SImmonds average, Dombrandt slightly above average, Randall was decent but there is a technical deficiency in his box kick because he seems to mishit about 50% of them
2) There are genuinely some big steps forward.. I'd say Sinckler could learn some from Genge, in that he almost seems too calm these days. Genge was monstrous, i thought underhill looked up to speed immediately, Itoje magnificent, and the hooker position of George/LCD is strong
3) In fairness, Steward as a tactic on the wing did work in attack, and he showed superb skills to finish, but Furbank was atrocious
On a negative side
1) Why was Furbank preferred to Malins, who is a much silkier runner, and deserved half a chance to show his ability in that position? This doesnt make a lot of sense, particularly with two playmakers already there
2) There is a lot of talk about a free flowing, heads up style attack after first few phases after set piece, but the biggest issue we've seen so far in this is the players have almost no idea who is carrying, where the ruck will be or how they're planning to play the game, ie touchline to touchline, set up middle of pitch and split the field, they're almost missing that focal point of the attack that you go to to get the momentum in your attack. I cant remember anyone bar Marchant straightening and attacking the line with the ball. But the biggest issue is if players dont know where ruck is or who's hitting said ruck, if they're running support lines, drifting wide, that ruck will regularly be under-resourced. Its a great idea in theory but im unsure if this free form attack will work even with more cohesion
3) Big need for a dominant back row. Dombrandt could develop into this with experience, he did run some really intelligent lines and could see him getting more game time, but Id think they really need the likes of a Barbeary in there, someone who's a real nuisance to bring down and draws defenders in. I'd also wondering if Cunderhill/ JWillis are about, would you put Lawes back in the row, not because i think its his best position but because you're trying to get the most dynamic players into the game to make an impact
4) Quirke from what I've seen is like Randall but with less glaring weaknesses, and seems to be smarter about how the team plays. Hoping to see him play in summer, Australia tour is usually a very good opportunity to work on attack because they usually play so fast and loose
