I didn't expect Nunez to play everyday, and I could see him and Pedey getting the most rest, once Pedey reaches his maximum comeback level. Maybe Moreland sits more, if he's down to his career .780ish level.
If Cora rests Betts, Beni, Bogey, Devers and JMart once every 20 games and Moreland, HRam, Pedey and JBJ once every 10 games, that leaves Nunez playing 13 out of 20 games. I guess that's close to enough. Maybe Pedey rests 3-4 games every 20, thereby giving Nunez about 3 out of every 4 games starting somewhere.
