In terms of matching salary, they can definitely get J. Smith from ATL for Bass + AB and filler. They also have the option of overpaying Bass slightly to make salaries match and sending ATL cash to make up for it.
Moore, JJJ, Sean Williams, AB = ~ 4.4 in salary - JJJ & Moore are on one year deals, and Sean Williams is not guaranteed.
Bass at 8m plus AB at filler can bring back about ~15.35m in salary.
If you take out AB, Bass and Filler can bring back about ~13.6m in salary.
