Why tracey needham only lasted one season of JAG?

Tracey Needham, who played Lt.jg. Meg Austin in the first season of "JAG," left the show primarily due to creative differences and the show's shift in focus. The producers decided to change the character dynamics, leading to the introduction of Catherine Bell's character, Lt. Colonel Sarah MacKenzie, which better aligned with the show's direction. As a result, Needham's character was phased out, and she departed after just one season.
