I'm going to take Moon's approach to 2018.
Just as he projected full year of Beni for 2017, I'm going to project full year impact of Devers. That alone should improve our offense for 2018. He can't do any worse than what we did early this year at 3B. Plus I can see few players having a bounce back year. Betts, Xander and JBJ can have better year in 2018 (assuming they don't go nuts over last 40 games this year).
By signing Moreland, we were able to leave enough cap space to add Nunez. We don't have to take same approach for 2018. We can blow past the tax limit.
Getting everyone healthy would go long ways in improving our outlook.
