You might have an easy time watching National Women's Soccer League matches online this season. The league has struck deals that give CBS Sports and Twitch the rights to stream games for the next three years. CBS will stream 87 matches, 71 of them available solely through All Access and its various portals through CBS' apps and website. However, the Twitch team-up may be the real highlight. Amazon's livestreaming service will air 24 "select" matches for free in the US on its channel, and it'll offer every game to viewers outside the US.
