A few quotes from Gary Kubiak about new Broncos QB Case Keenum, from this Houston Chronicle article:
The reason he’s where he is, first and foremost, is his work ethic. He wants to be great. His presence among his teammates is as good as I’ve ever seen. He never judges people or acts like he’s above them. He treats everybody the same, and guys want to make plays for him.
Case played well (in his rookie year), but we couldn’t win a close game. One thing I learned about Case is that he’s such a mentally strong person. He can handle any type of locker room and any kind of teammate. He’s very consistent on and off the field. His teammates respect that.
A lot of guys would just go in the tank with a start like that (0-8), but Case kept battling because that’s the kind of guy he is. He’s very comfortable in his own skin.
I don’t care who he plays for, you’re not going to put Case in an uncomfortable situation. He’s got a lot of confidence in who he is and how he carries himself. Guys respond to that.
