The Adams conjecture states that the local theta correspondence sends a local Arthur packet to another local Arthur packet. M{\oe}glin confirmed the conjecture when lifting to groups of sufficiently high rank and also showed that it fails in low rank. Recently, Baki\'c and Hanzer described when the Adams conjecture holds in low rank for a representation in a fixed local Arthur packet. However, a representation may lie in many local Arthur packets and each gives a minimal rank for which the Adams conjecture holds. In this paper, we study the interplay of intersections of local Arthur packets with the Adams conjecture.
