"It's like baseball," CBS Evening News anchor Bob Schieffer tells Ed Bark. "You've got to put 'em into the game to see if they're any good. And we're finding some really good ones." Some of his favorites:

Lara Logan: "She's the next Barbara Walters. In addition to being very smart, let's face it, she's beautiful."

Lee Cowan: "All of a sudden he's coming into his own."

Sharon Alfonsi: "She's funny as hell."
