The Cubs have to balance two of the strengths that make them incredibly successful: Out of this world defense, and a patient offense that grinds pitchers to dust. Almora and Baez help a lot with the former, but probably are never going to be all that great at the latter, even if they're good players. Zobrist isn't going to help a ton with the former, but he's incredible at the latter(and probably the best hitter on the team outside Bryant/Rizzo/Schwarber). This is not really much of a problem though, as the odds of the season progressing without any of Rizzo/Bryant/Russell/Schwarber/Heyward needing days off or getting hurt are not very high, and then you have no logjam outside of Jay(who is nice, but who cares if he's benched),
