Broncos free agency: John Elway says Denver is still trying to re-sign Mitch Unrein

He's no tight end, but Denver seems interested in Mitch Unrein anyway.

Broncos general manager John Elway said Wednesday that they are trying to re-sign the versatile defensive lineman.

Unrein played defensive tackle during his first four years with Denver. In Wade Phillips's 3-4 defense, Unrein would likely play defensive end, according to MHR's Scotty Payne.

Unrein has also played fullback at times, but he is not an ideal fit as an every-down blocker.

He entered the NFL out of Wyoming as an undrafted free agent in 2010. He went to camp with the Texans (under Gary Kubiak) after the draft and later signed with the Broncos. He made his NFL debut in 2011 and has played in 49 games since then.

Unrein is a rotational defender at best and a special team's contributor at worst. At the right price, he's worth bringing back.
