There are games where Snit makes questionable moves that fans like us call-out and realize are suboptimal. There are games where he ignores analytics and makes blatantly wrong decisions.
Yesterday was particularly embarrassing in that it doesn't fall into any of those buckets. Even 1990's style managing would know that with a pitcher around 100 pitches laboring, and a lefty lefty match-up available, that would be the way to go. That's not new school analytics, that's classic old school baseball managing. That's what makes it stand out as so bad. This was Snit truly defying the most tried and tested baseball managing school of thought that still holds true to this day (even if more advanced analytics have further helped optimize this type of decision such as third time through line-up, etc)
Yesterday didn't feel like watching a manager that is suboptimal, it truly felt like watching a manager that was just clueless.
But ultimately it's just poor leadership by an organization to tolerate this year after year. Even if one concludes Snit is a good manager because of some "chemistry dynamic" that he brings, no employee should ever be above constructive feedback to get better. With Snit the repeated mistakes are just so consistent that it is 100% evident that there has been no element of constructive feedback along the way. If they've concluded we can't fire him for various reasons, I can get my arm around that. But it's just embarrassing leadership to conclude that any employee is above basic feedback . Heck Tom Brady is the greatest football player of all time and for 20+ years the guy took daily criticism from his coach to get better.
