A) I'm overcomplicating it in response to you oversimplifying it. How has Codi been substantially better than CJ down the stretch this year, outside of him winning us two games against really bad teams? Likewise, I told you that a more holistic measure of improvement takes into account the fact that one guy did what you are claiming two guys replace (when combined), basketball IQ (aka facilitation ability) and defensive ability. The latter two, I admitted are based on subjective opinion, but I don't think many feel like Codi and Coron trumps CJ in either regard. I could be wrong, though.
B) I'm wondering if we are actually clearly better. Perhaps the kenpom folks can weigh in on this. We are ranked lower now than we started this season despite an easier schedule. I see our guys looking good against shitty teams and more or less playing to low expectations against good ones. I've showed this in splits with Codi and Devin, but it's true for Cav, Coron, and Travis as well. I see only CMM really trumping preseason expectations on the basis of per-40 pace adjusted and even he is regressing to the mean as the level competition has increased (and even against teams that are not very good).
