Former Lions running back Theo Riddick is scheduled to visit the Broncos, a source tells ESPN.com’s Adam Schefter (on Twitter). This marks the second visit on Riddick’s free agency tour after he huddled up with the Saints on Sunday. 
The pass-catching specialist had some excellent years in Detroit, but the rise of Kerryon Johnson lessened his importance with the Lions. When the club signed C.J. Anderson this offseason, it was yet another indication that they could move on from the 28-year-old.
The Broncos already have a No. 1 running back in Phillip Lindsay, but Riddick’s soft hands could make him a strong No. 2 companion. Last year, Lindsay caught 35 passes for 241 yards and a touchdown out of the backfield. Riddick, meanwhile, has averaged a 62/474/2.5 stat line over the last four years, including a showing of 80/697/3 in 2015.
In addition to the Broncos and Saints, the Vikings are said to have some level of interest in the veteran.
Am I missing a story they explains why Royce Freeman isn’t in this articles discussion?
Ya, I’m not quite sure why he isn’t mentioned.
Also not sure what the Broncos see in Riddick unless they are worried that Lindsay won’t stay healthy and then a pass catching back would be needed to complement Freeman? Even then, I’m sure they could find a cheaper option for somebody who likely won’t take more than a handful of snaps all season.
