While the lineup of content is still being sorted out, the Pac-12 says streams will cover events in Olympic sports of soccer, volleyball, gymnastics, baseball, ice hockey, swimming and diving, softball, track and field, wrestling, lacrosse, tennis and water polo. You'll notice that football is absent from that list. No, it's not an Olympic sport, but it is the most popular college athletic action besides basketball -- which also isn't mentioned. Those two sports typically command big money television deals, so it's understandable if Twitter couldn't nab those rights as well.
