I agree with your post almost entirely, but I have some perspective differences.
it’s clear Rocco has to manage pitching differently than I want him to. The starters were a triage due to the FO’s mismanagement in the off-season (and prior off-seasons). It seems that many of us at TD agree on this point, and would like the starters to go deeper, the bullpen to be less taxed, but they just don’t have the horses. Seems like we agree on this point.
The Selig ball, designed to increase scoring by increasing home runs had been in place for 15 years or more. The specter of Bonds, McGuire and Sosa loomed over baseball until the Manfred ball. Player coaching had been centered around fly balls and pull-centric hitting. That includes fielding, and situational hitting.
Rocco can’t just drill MLB players in 2 off seasons enough to undo 10 years of coaching from High school through several years of minor league ball and other organizations coaching too.
Rocco doesn’t call for small ball situational plays because they haven’t been coached heavily like they were when I was in highschool.
Rocco has to work with the roster he has. As we saw in news articles, Rocco and the FO are stressing baserunning and steals in the minors this year. They’re adjusting to the Manfred ball becoming permanent. That takes a few years.
I like Rocco as a manager, but unlike last year, this team seems to have gotten flat during the August doldrums. If he can’t get this team to snap out of it quick, the FO needs to look at options. I doubt they find better ones, but they need to look.
