The closer we get to the draft, the harder it gets to figure out how things are going to fall. Rumors are always swirling, and analysts contradict each other and—from time to time—themselves. Stocks rise and fall on a daily basis. Guys who looked like locks for the first ten picks drop out of sight, and players that you've never heard of storm onto the scene.
It's something that's impossible to predict with any reasonable accuracy, but there is one thing that can be done: plotting potential targets. It's easy enough to see where the holes are for some teams, and you have to think they'll target those types of players in the draft.
Of course, crazy things do happen. Teams take guys in the first round that are not on anyone's radar.
For the Broncos, though, without too many glaring needs, the draft should be fairly straightforward on that first day. The team will have its top targets, and it may even move up to get them if it looks feasible.
