JRich was fine defensively before COVID, as was Maxi... hopefully they can improve with time on that end.
If it's a choice between Brunson and JRich though, the Mavs will have to make that decision fairly soon, or risk losing both for nothing. In terms of teams where a trade for JRich would make sense, I've suggested the Raptors before; he would fit in nicely next to sharpshooters FVV and Anunoby. The earlier trade was JRich+Burke+WCS for Lowry and Boucher, but Lowry wouldn't make sense if the plan is to clear the path for Brunson to start (I'm also not sure that would be enough for Lowry). In that case, here's a smaller JRich + WCS for Boucher trade. Boucher would fit in nicely as the 4th big who could play with any of the others.

Mavs would still have Johnson as a trade piece after that, and would be looking for wing/guard depth. Maybe a trade with Miami for Dragic?

New lineup:
Luka / Dragic
Brunson / THJ
DFS / Green
Maxi / Boucher
KP / Powell
