Michael Sam is power rankings No. 1

Many athletes excel at their sports. But only a precious few can look back on their career accomplishments and say they truly "changed the game."

There's no guarantee that Michael Sam will become a star in the National Football League, even though the AP named the defensive lineman the SEC's defensive player of the year. But what Sam did Sunday -- telling the world that "I am an openly, proud gay man" -- just might have changed the game for gay athletes across American sports. And that makes him No. 1 in this week's Cross-Sport Power Rankings.

Joining Sam in the top five are Kevin Durant, making his fifth straight appearance in the CSPR, biathlon gold medalist Ole Einar Bjorndalen of Norway, Iowa State's Melvin Ejim and Team USA snowboard gold medalist Sage Kotsenburg.
