Sure. To me, there's only one big problem - the "2x thru" rule. If he were more aggressive about adhering to the "2x thru the order" rule, how bad would he be, tactically?
There aren't that many other buttons to push. We're not built to platoon much. Bench has been good but they're of minimal utility because most of the team plays 155 games.
Your bullpen either gets outs or it doesn't. Last year they got lots of outs, this year they didn't. Will Smith is maybe the sixth best reliever this year (and last, for that matter), but Snit's boss paid him $39M to close. So he rides him until the bitter end.
We have a harmonious clubhouse. Players love him.
He at least professes to try to use new metrics. If I have concerns about lineup construction, they're reduced by the limited importance of lineup construction and the fact that we have a lineup full of guys with no clear OBP option.
So what's to hate? Every fanbase thinks their guy is a moron. Snit's not a rocket scientist, but I'd rather have those guys building rockets and Snit building the clubhouse and lineup card.
Other thing is, even if you want him gone, he's not going anywhere. He's won four straight divisions and the team is showing progress in the playoffs. He might get another extension after this one.
