When we look back on 2015, there's a good chance we'll remember it as a groundbreaking year for women in sports. Not only were women killing it on the pitch, on the court, in the pool and in the octagon, but also on the sidelines and in the broadcast booth. Everywhere, it seemed, women were making inroads in sports.

Hopefully along the way, they also inspired young women around the country to believe in themselves a bit more, and changed some minds, too.
