Fast National ratings for Sunday, March 30, 2014.

A tight NCAA Tournament Elite 8 game stretched 20 minutes into Sunday primetime and boosted CBS to primetime-winning numbers in all key measures.

Meanwhile, all of Sunday's new programming continued to drop with weekly declines for "Resurrection," "Cosmos," "Believe" and "Crisis."

If you're looking for some good news, ABC's "Once Upon a Time" posted a small gain among young viewers, though "Revenge" was down week-to-week.

[We'll have "Walking Dead" finale ratings later in the day. They'll be higher than anything on-network.]
