Consider this a sort of football version of myth busters. But as the Denver Broncos were busy making it rain in the opening days of free agency with five signings, four of those of the high-profile, get-some-headlines variety, much of the national conversation was about how the team pulled it off.

And there is no real mystery. The two biggest reasons the Broncos were able to do what they did:

They planned for it. Their salary cap situation was, and still is, better than most thought.
Winning is a powerful lure. Players are willing to structure deals that will pay them if they succeed, but also fit into the Broncos’ big picture so the team avoids the one-shot, mammoth signing bonus that eats the future cap room if things don't work out.
