The Kansas City Chiefs are 1-3 and the organization is losing confidence in Matt Cassel.

Cassel has five touchdown passes and three interceptions this season despite playing fairly average or below average defenses over the first four games.

"Look, there's a big reason why they went after Peyton Manning as hard as they did this offseason," said a source with knowledge of Chiefs president Scott Pioli's thinking. "What you're seeing from Cassel is pretty much what was expected. He's a really nice backup, not a starter."
