I think nutterforthree's point that nearly everyone is playing "worse" than last year is a bit hyperbolic, as you point out with each player, but why have nearly all players not taken any significant progress forward? Is there often not an "expected" jump between freshman and sophomore years, for example?
There were many who were excited when Middleton and Dual committed, but has Coach Sha really gotten anything more out of them than did Chris Holtman or Kim English?
Aligbe was the first commitment from Coach Sha in the off-season, for which I was intrigued. He's a junior now and does not look like he's taken any step forward at all. If you aren't going forward, you're going backward.
Toumi, a late commitment, was also viewed as someone who would contribute immediately in the front court, having averaged over ten points, six rebounds, the last two years. He even shot 54% from the field last year. This year, 5.7/3.5 in 20+ minutes per game.
And maybe Wusu doesn't look better or worse but, as you even point out, maybe he's not being put in a position to be most successful.
Keep in mind that all of this is against a strength of schedule thus far which KenPom currently ranks as 269th. One would expect better numbers now, with a regression to the mean later once conference play starts.
Believe me, I'm far from a negative poster (and do believe that the team will get better). But I think it is at least fair to ask 10 games in whether this team is being put in the best position to be successful.
