The Broncos then went on to sign tight ends Joel Dreessen and Jacob Tamme.
Former Saints cornerback Tracy Porter became a Bronco as did former Bengal wide receiver Andre Caldwell.
Denver wasn't done. They added former Bear quarterback Caleb Hanie, who will now serve as a backup to Manning.
With all the signings and changes to the roster, what positions do the Broncos now need to fill in the draft?
Here are five needs that the Broncos must address.
The Broncos roster at the quarterback position is entirely new.
Gone from 2012 are all three quarterbacks Kyle Orton, Brady Quinn and Tim Tebow.
New to the team are Peyton Manning and Caleb Hanie, both free agent signings.
Manning just turned 36 years of age and Denver still needs a quarterback to groom for the future.
Brandon Weeden out of Oklahoma State may be someone in whom the Broncos would have an interest.
Other prospects: Brock Osweiler Arizona State, Kirk Cousins Michigan State, Kellen Moore Boise State.
The Broncos were very interested in former Colt center Jeff Saturday.
Now, some of that may be because Saturday is a buddy of Peyton Manning.
But I have a feeling that John Fox isn't all that enamored with current Bronco center J.D. Walton.
Don't be surprised to see Denver take someone like Ben Jones out of the University of Georgia.
Walton should maintain his starting job for awhile but it may just be a matter of time.
Other prospects: Michael Brewster Ohio State, Moe Petrus Connecticut
One position that the Broncos have not addressed through free agency has been running back.
While the Broncos do have some running backs on their roster, there may be more questions than answers.
Willis McGahee will turn 31 this year. How long can he play at last years' level?
Will Knowshon Moreno ever live up to his potential?
The Broncos need to solidify this position through the draft and there are some players out there who could fill their needs.
Lamar Miller from the University of Miami is an explosive playmaker who could give the Denver backfield a lift.
Other prospects: LaMichael James Oregon, Chris Rainey Florida
Denver is going to have to address the position of strong safety.
The brilliant career of Brian Dawkins appears to be over.
David Bruton and Rafael Bush are not the long-term answers.
That means the drafting of someone like Mark Barron the strong safety out of Alabama.
Barron will cost a higher pick but he is someone who can step in from day one and compete.
Barron is a big hitter with a knack for making big plays.
Other prospects: Antonio Allen South Carolina, Sean Richardson Vanderbilt
Without a doubt, defensive tackle is the Denver Broncos No. 1 priority in the 2012 NFL Draft.
The position was already weak.
Then Brodrick Bunkley signed with the New Orleans Saints further lessening the group.
You may be wondering... why I have only chosen five positions for six picks?
Spend two picks on the defensive line.
Fletcher Cox out of Mississippi State would be a nice addition. Cox had a great combine and managed five sacks in his final season in college.
Other prospects: Michael Brockers LSU, Devon Still Penn State
