No one really focuses on batting average anymore.  It doesn’t correlate directly with scoring runs. Look at OBP and slugging.  That said I don’t think you can expect Coles to turn miracles with guys. For Abrams and Garcia it’s their first full year in the big leagues so there will be ups and downs. That is why it is silly to talk about windows for contending when some of the guys in the minors now will first hit the big leagues. There is an adjustment for most. Nats fans were spoiled by guys like Harper and Rendon. They are the exceptions and not the rule. Same for pitchers. Look at how much better Gray is pitching this year.
