No idea what you mean by 'using stats as a barometer is a mistake'. You said we have an inability to create chances. Yet throughout the season as a whole the evidence shows that to be untrue. Take either an inference like expected goals or take a plain old measure of the total number of shots or shots on target. The answer is the same. And those outcomes are driven by the play that we observe for 90 minutes. So I wouldn't go around treating measures of what happened and perceived 'gameplay' as somehow mutually exclusive.
Agree on the change relative to start of the season, but I think we were still in the period until the derby. That was December, so less than two months ago. Now I see a team that is trying to find the balance, with some key players out of form, and agree it can look stagnant at times. Where we differ I guess is that I think we are broadly on the right track.
