I think the Cam Johnson story is a lot of clickbait and very little reporting. It only mentions good teams, ALL of whom supposedly want the same guy.
Technically there is likely SOME truth that teams have talked, because they all check in with all the others almost every day to gauge who might be available. But that doesn't mean all (or any) of those mentions of CJ were meaningful. I would wager some - maybe most, or even all - of those talks were primarily about some other Net. Schroeder just got moved, the Nets are clearly sellers so probably anyone can be had at the right price, and probably all their players are named at some point with everyone who calls.
TL/DR. I doubt the Mavs have any serious interest in CJ, even if his name happened to be mentioned in a convo.
