It's easiest to take your points one-by-one, so that's what I'll do.
It's up to players to play with energy and make make plays, but when we have game after game and season after season of different players not playing with energy and not making plays, then the ultimate blame lies with the coaches. And, on the whole under HD, a wide variety of players have consistently not made the plays. Again, this is back to the it's not about "one game" or "one season" excuse...our team failing to play up to their talent level is a consistent issue under HD.
I think that HD has likely improved as a coach during his time as HC, but it's not been enough to make a difference in our overall performance across multiple games and seasons. If someone isn't meeting the base level goals, it doensn't really matter that they're only failing by 25% rather than 50%.
My issue with enjoying games is that we have many of the same problems over the last 5 games that we had over the first 18 games of the 2021-2022 season...the team simply doesn't seem to play hard, smart, and together in a way that both maximizes their individual abilities nor the ability of the collective team to succeed. Again, I have little doubt that HD is a better coach than he was when he was hired, but he's not improved enough that the team is consistently successful.
I find this season (and nearly every season under HD) utterly frustrating. Our players are clearly talented in total and each player has skills that should contribute to team success, but the performance of the team, in total, has been and continues to be that we don't play well - either against our potential nor against actual opponents - on a consistent basis. The second half of yesterday's game was a lot of fun, but that kind of collective performance has been rare under HD. And I have little evidence that the next half or the next game or the rest of the season will show similarly good performance as we saw in the second half yeasterday, which makes it pretty hard to be excited about that half or that game or the rest of the season.
I don't think you can find 10 P5 coaches that are consistently satisfied with their team's effort.
I think fans' "goals" are often a product of selective memories. We romanticize the past without remembering the struggles. Coach Smith had down years. Coach Williams had down years. Nobody will ever go to 13 consecutive sweet sixteens again.
My assessment of Davis's improvement differs from yours. I see it in halftime adjustments. I see it in plays out of timeouts. I think it has made a difference in overall performance.
For me this season isn't nearly as frustrating as the Caleb Love/RJ Davis era. If you want to avoid frustration, I suggest a different hobby instead of college sports.
Several posts, including yours, have mentioned consistency. 18-23 year old American males is a bad place to look for consistency. As donbosco pointed out, COVID, NIL, and the portal have had a major impact. Kentucky, Kansas, UCLA, Purdue, and Michigan State have been inconsistent game to game and year to year. Carolina has won more ACC games in Coach Davis's tenure than all but 1 team. That is, if not consistent excellence, at least consistent really-goodness.
I get your frustration. I don't understand some lineup decisions. Last season I wanted more Withers at the 4 and Powell at the 3. I'm finally getting more Dixon and less Evans, but I still want more Powell. Lack of defense for 4 straight games. Poor 3FG and FT shooting. I understand, however, that there is only so much a coaching staff can do.
I also don't have any confidence that a new coach would be better. Who? Dusty May or TJ Otzelberger? Unless you think Mark Byington is ready and willing... Hard pass on the Nate Oats, Scott Drew and Todd Goldens of the world.
You may consider me a sunshine pumper. I don't. Maybe I have an advantage because i'm not surrounded by other Carolina fans. I'm not subject to groupthink in that regard. You guys (and ladies) are my Carolina family, and I appreciate the diversity of comments. I just think that this team is fun to watch, and I can't think of anyone realistically that I would rather have coaching this team than Coach Davis.
