Players should have at least good fundamentals by the time they are in the big show. When they hit Farrell, players should at least know and be able to execute the fundamentals of both fielding and running without even thinking about it. At the top level they shouldn't be going over basics, and we aren't even seeing basic stuff done well. Farrell shouldn't have his staff talking about when to tag up, or when to hold the ball, or how to take a lead. He should be talking about how to maximize that stuff.
We aren't even seeing the basics done well from these players. I can't blame Farrell for that.
If you want to talk about why these players are not remembering the basics when under pressure, I would consider that.
But blaming Farrell for people thinking a pop fly is going to be called an infield fly rule, or Hanley not seeing Benny at second, or some third baseman throwing away a ball instead of holding on to it, just doesn't make sense to me.
