I think it's great that women are becoming more visible in sports coverage, but the answer to your question is: definitely still second fiddle. Look at the positions that most female nba media personalities are employed in: sideline reporting and brief studio spots that are more focused on delivery than analysis. In other words, these women still aren't being invited to offer analysis and perspective, they're just there to deliver lines (and based on what I've seen for female csnne and celtics.com correspondents, conventional attractiveness and physical appearance seem to be as much of a factor in gaining employment as interviewing skills or actual basketball knowledge).
Jackie Mac is a personal idol of mine, but no matter how much knowledge she has, she (and women like her) still aren't being invited to the halftime table. Until major sports media stations like ESPN, TNT, ABC etc include women on their analytical panels in pregame and halftime shows that focus on actual sports knowledge rather than token appearance, it's not really much of a step forward in my eyes.
(I'm speaking specifically of the NBA--I've never been interested in NASCAR so I can't speak to that.)
