I think, conceptually, the only way to statistically say the offense is broken is by looking at what they did in August. Like, here are some assorted sample sizes of the teams offensive production in terms of how they rank league wide.
YTD: 4th in fWAR, 10th in wOBA, 4th in xwOBA, 5th in wRC
June 1-July 30: 3rd in fWAR, 5th in wOBA, 1st in xwOBA, 3rd in wRC
July 1-July 30: 3rd in fWAR, 5th in wOBA, 1st in xwOBA, 4th in wRC
July 1 -today: 16th in fWAR, 22nd in wOBA, 4th in xwOBA (hm), 20th in wRC
August 1-today: 23rd in fWAR, 28th in wOBA, 7th in xwOBA (hm again), 26th in wRC
So really you've got a month of them having at least (very) bad results. Should we give it slightly more weight because it's the most recent month? Sure. Is it dumb to throw away the season based on a months sample size when we still have a brand new sample size of a month that we basically haven't played yet? I kinda think so. If we spend September with bad results/bad metrics, and I'm having to defend them as like 'we'll, they're just playing out the string, making sure they don't get hurt'....I'm going to feel worse about their chances.
But, since you asked for optimism/pessimism:
Optimism: We're into September and Matt Boyd and Cade Horton's collective arms are still attached to their shoulders, offensive production can turn quickly and all signs are saying that it should, and I think the talent is more than sufficient on that side of the ball.
Pessimism: By far the biggest: there are 12 teams, only one can win, there is a 90% chance it won't be us and everyone who shows up in the game threads when we go down 2 runs can gloat about how they were right to be miserable all year. More specifically, we have like 5 good pitchers, and that doesn't seem like nearly enough.
