JD isn’t a DH in mindset, yet. Throwing him in the OF every now and then definitely helps his psyche and allows other players some rest. Cora definitely subscribed to the theory of ensuring all players, not just the fragile or old, need scheduled rest. And if JD is going to give his best defensive efforts out there, it won’t be once every 10 games, he’ll have to see the field more often.
Either way, your squad’s OF defense is impressive. The question becomes, next year, when Pom walks and you tie up Kimbrel with a big contract, does JBJ get moved for an arm to slot into your rotation.
