"Stanford has already started living up to monumental expectations with a good first game": I'm not sure where the "monumental expectations" comes from; Stanford finished below .500 last year and was picked 9th in the Pac-10 preseason media poll.
"Stanford defeated San Diego with domination in offensive rebounding and an additional beat in possession management.": Not sure what "an additional beat in" means here.
"Stanford has incredible expectations for this season, and this victory over Cardinal was a good start.": Should be "over the Toreros" or "for the Cardinal".
Overall, though, it's pretty slick.
