I think keep Robert's
I'll teach Kershaw how to throw the change up
Kick machado to the curb, he sucks
But most importantly Robert's needs to tell the nerds upstairs... "Thanks for this binder full of analytics. They'll be a useful tool in my arsenal but please let me do my job, mmkay thanks."
This is baseball
Roberts needs to be more than a cheerleader if he wants a ring. He needs to take his job back from the front office.
I have no issues with relying on analytics during the season. It's obviously worked with 6 straight NL West wins.
The issue is that things change in the post season. Emotions and adrenaline become more influential. That's why every year, every team; a journeyman player steps up to become a mvp and a regular season superstar goes 2 for 20.
The post season is made up of 7 (or 5) game mini seasons. There's not enough time for the analytical averages to work themselves out. You have to rely on the hot hands. Cora understood this, that why they won.
I think the only one who managed worse then Roberts, in the post season, was Counsell.
