For some well-known Broncos, this is it. The game Sunday at Oakland will be the last time during the regular season a few players headed for unrestricted free agency will wear a Broncos uniform. There will be another one, two or three games to play in the postseason, but regardless of how long the Broncos survive in the NFL's single-elimination tournament, the end for some is near. The Broncos have 16 players headed for free agency, including 12 who have started at least one game in 2013. The list ranges from every-game offensive starters Eric Decker, Knowshon Moreno and Zane Beadles to veteran backups Quentin Jammer, Michael Huff and Winston Justice. The way it works with free agents in the NFL's salary cap economy, it's often the better players who are the most difficult to re-sign. "You always have some interesting decisions to make, especially if you have a good football team," said John Elway, who heads the football operations department of the 12-3 Broncos. "The better you are, the harder the decisions." The defending Super Bowl champion Baltimore Ravens are the latest example. A month after celebrating in New Orleans in early February, the Ravens parted with prominent starters Anquan Boldin, Dannell Ellerbe, Paul Kruger, Cary Williams and Ed Reed largely because they couldn't afford them. Exactly which players will be re-signed and which will move on will be decided by Elway's football operations department, and in some cases by the players themselves. The 16 Broncos who are eligible for unrestricted free agency: Decker, wide receiver; Moreno, running back; Beadles, offensive guard; Shaun Phillips, defensive end; Dominique Rodgers-Cromartie, cornerback; Wesley Woodyard, linebacker; Mike Adams, safety; Robert Ayers, defensive end; Paris Lenon, linebacker; Andre Caldwell, wide receiver; Chris Kuper, offensive guard; Quentin Jammer, cornerback; Jeremy Mincey, defensive end; Michael Huff, safety; Steve Vallos, center-guard; and Winston Justice, offensive tackle.
