Well it is a long time till april and I am sure we will learn more about the players and who will leave school early but this is what I would have in mind for the Broncs.
Assuming Mario Williams and Ngata come out, one of them or Kiwi, ro Rod Wright should be available for pick 1A.
With 1B I would target Hagan (I really don't have much of an opinion on him, but he has the measurables) or an underclassman Wr if there were any worth the pick If not I would go OG with Jean Giles, Joseph or Elsinger as the targets.
If 1B was not an OG there are a few to target in round 2 Raiola, Scott and Degory come to mind or perhaps one of those I emntioned at 1B will fall
As I have said before, Safety can be easily addressed in FA.
