"He doesn't recruit...PO's".. , regarding competition. A PO who competes every single pitch vs. a position player who competes 20-30 plays/at bats a week. I'd say it's at least equal on that level. Sounds more like a philosophy he just made up in his head rather than one that has any sound reasoning. IF he just said he needs to make sure he has flexibility on the roster, I'd take that...but I'd take the mental toughness and compete level of a pitcher over a position player any day of the weeks. Besides, compete level is really an individual thing, not a position thing.
Despite being a former PO, there is no bias in that opinion whatsoever
