By no means is this meant to be a definitive list, nor does it come with the scheme-aware analysis that Ted, Doc, and TJ can offer. But as we await the opening of free agency, here are a few names potentially worth keeping an eye out for:
Austin Collie - Only played one game last year, and has had notable concussion issues. Still, he thrived with Peyton Manning, so why not sign him to a non-guaranteed contract and have him compete with Brandon Stokley?
Terrance Knighton - He was drafted by, and played under, Jack Del Rio for his first three years in the league. He's currently listed at 330 lbs, and Del Rio made it well known last year that he prefers heavier tackles. Knighton's weight may be what keeps his price down, so isn't this a natural fit?
Dwight Freeney/Osi Umenyiora/John Abraham - If the Broncos are to replace Elvis Dumervil with Robert Ayers and a cheaper pass-rush specialist, either of these players would make sense.
Kevin Vickerson - The team reportedly wants him back, but he wants a raise, a year after he accepted a huge pay cut to stay in Denver.
Greg Toler/Antoine Cason/Dominique Rodgers-Cromartie/Sean Smith/Chris Houston - It's widely assumed at this point that Denver is again looking to find an outside starter to pair with Champ Bailey. They visited with Dunta Robinson before he signed with the Chiefs. Between reports from Mike Klis and Mark Kiszla, the Broncos are considering these five corners.
Shonn Greene/Steven Jackson/Rashard Mendenhall - Are the Broncos as serious about getting bigger at running back as Jeff Legwold has maintained for two months now? We're not so sure about that, but there's been speculation that the team has expressed interest in these guys. If Denver signs one of them, that probably means Willis McGahee gets cut, right?
Reggie Bush - Ted made the case for pursuing Bush yesterday, and it was a lot better thought out than what I'd written earlier in the day, so let's go with that.
Wes Welker/Danny Amendola - Could the Broncos choose to go with one of these bigger names to fill the slot WR role instead of Stokley/Collie?
Chris Canty/Derek Landri - Landri had visited the Broncos in 2011; Ted liked Canty for Denver in 2009, but that was several schemes ago.
Brandon Moore - If the Broncos want to leave Orlando Franklin on the edge and upgrade over Chris Kuper's questionable health, Moore would make sense. He'll turn 33 in June, so he won't command a big deal.
