Yeah, I doubt Vance Joseph - Denver’s black head coach - has any hidden agenda in saying “no thanks” to Kaepernick. Osweiler isn’t much good, but he knows Denver’s offense and the players there. Kaepernick would need the offense to be changed to suit his peculiar style.
Plus Denver got Brock for $775K. Colin wants starter money. If he would have taken less he would probably be in Seattle now.
