Ms. can also be a generic article, much like Mr. is for men.
If it was just mentioning her and not that she was
the wife of Avery Johnson, it might make sense, but when referencing a woman like the article did it would be Mrs. and not Ms.
Note that the original article posted did not call her Ms. - two posters did.
The only articles I found discussing the incident used the title of Mrs. Johnson.

As if the Mavericks didn't have enough problems with their 20-point loss at Phoenix Tuesday — only the third loss all season of 20 or more points — Cassandra Johnson, wife of coach Avery Johnson got into a fracas with a couple of fans she believed were standing too often and inhibiting her view. Reports have witnesses saying she took a couple of swings at the woman and actually made contact with the man, then sought out security. The couple filed a misdemeanor assault charge against
Mrs. Johnson. In the process, Mavericks owner Mark Cuban, Mavs director of security Jim Colleran, strength and conditioning coach Bob Hackett and reserve center D.J. Mbenga also entered the stands — which could prompt consequences from the league pending investigation.
