Even with the “voluntary” billing, it was a packed house at Dove Valley for the Broncos’ recent OTAs.

Now comes the not-so-voluntary minicamp.

The team’s mandatory minicamp is Tuesday through Thursday, and the Broncos are aiming for perfect attendance.  Players under contract who are no-shows are subject to fines.

Only one veteran, kicker Matt Prater, remains unsigned.  The Broncos placed the franchise tag on Prater in March, and are now reportedly working on a five-year contract.  Prater did not participate in the team’s OTAs.

Rookie contract update

The Broncos are also working to sign rookie quarterback Brock Osweiler, taken in the 2nd Round at No. 57 overall and third-round running back Ronnie Hillman, the 67th selection.
