Kaepernick would be the better choice as a player, in my mind. He is a bit too controversial at the moment for Elway. Well, I think, anyway.
If they could pick him up on the cheap due to that, and Kaep decides to take his protests to some less controversial places and dedicate some personal time and money toward his beliefs, he might be the best candidate.
Otherwise, I think I'd go with Geno. He just seems to need some team to believe in him, find him some receivers who he clicks with, and teach him some confidence through his very qualifying abilities staying on a positive note.
Geno is a little younger than Kaep, as well. He might be a longer term prospect worth the time and effort to train him the Broncos way of playing.
My humble, probably mistaken opinion.
