Eh - I don't really see that. Shooting was an issue for the 2022-23 team, when basically everyone except RJ disappointed. It has not been an issue for the others, including last year's.
i agree with your larger point but shooting has absolutely been
an issue for more teams than just the 22-23 one. Last year's team was a mediocre shooting team at a team-wide 35.6%, which isn't bad in a vacuum but they were always going to have to be much better than that to have much success with how the roster was constructed. That number is also boosted by RJ Davis and Jae'Lyn Withers catching fire late in the season after most of the damage had already been done - up until the month of March, RJ was a mere 31% shooter leading the team in 3-point attempts per game (he finished the season at a respectable 35.4%), and Withers was at a decent percentage but was taking less than two attempts a game (finished at 2.4). Cadeau, Trimble, and Tyson were all bad shooters after offseason promises of the contrary, which made them difficult-to-impossible to play together without killing spacing. Jalen Washington's small sample size of floor-stretching disappeared, which made him basically unplayable. So for a large portion of the season, the only reliable shooting we had was the two freshmen, and even they were pretty streaky.
The 23-24 team was mostly fine but it was probably held back from being better than it could've been by Cadeau and especially Withers' shooting regression from their previous years of playing basketball - that said, Ingram's positive shooting development was a positive sign for the staff.
The 22-23 team, you covered, and the 21-22 team is the only HD team I'd really say didn't have an issue with shooting in conjunction with its roster construction.
Again, in a vacuum, all of his teams have been around 35-36% shooting, but who is doing that shooting matters, as well as players' shooting development. And IMO Hubert and staff haven't done a great job with both of those aspects.
I often think about an anecdote told by a play-by-play guy in one of the earlier years of HD's tenure - a player mentioned wanting to spend time with his old shooting coach, and Hubert sat all the players down and basically said "I'm the best shooter in UNC history! You know who's second best? Coach Lebo! What do you think you're going to get from a shooting coach that we can't teach you!" IMO, that's both a worrying indicator particularly of the shooting development of this staff and emblematic how of HD's refusal to consider outside perspectives hampers him and the program. I don't think it's an accident that the best shooter he's had has been Brady Manek, who had 4 years of shooting development by another coach. The kind of jump shot taught in the 80's and early 90's that both Hubert and Lebo used doesn't really play in the contemporary version of the sport.
