I have always thought that they were allowed to show highlights during sportscenter, but that was the only place that was allowed to show highlights. Thats why you have clips from other games, and you have Non-CBS new stations using puppets to re-enact games... saw a thread on here about that if I recall corectly
anyway not sure of the legal reason behind it but thats basically what is allowable from what I've seen. Which is wierd.
also I think after each round is played out, CBS releases the video so now they can use games from last week to analyze the teams this week
