Tim Tebow insists that he'll be a quarterback in the NFL one day, but he's willing to line up wherever he can help the Broncos. He lined up as a slot receiver last Sunday when Denver's group of receivers was beset by injuries. "Well, I want to be a quarterback. I believe I can be; I believe I will be. And I've just got to keep working at that," Tebow said. "But if I can help the team in another way, that's what I'm here for. "You know, we're all football players first."
