Kubiak wants to add fourth QB

The club remains in the market for a QB to play behind Matt Schaub, T.J. Yates and rookie Case Keenum. "I think I'd like to sign a fourth guy," said coach Gary Kubiak. "With Matt being out, with the 90-man player roster, I think there's room for that guy." Kubiak added that while the team likes the crop of youth at WR, adding a veteran remains a strong possibility.
