Assuming he finalizes his agreement with Denver, Riddick will bring a different dimension to the Broncos backfield.
Phillip Lindsay will open the year as the starting running back and primary ball-carrier, having run for 1,037 yards and nine touchdowns en route to the Pro Bowl as a rookie. Royce Freeman is a dependable No. 2 option as well after he ran for 521 yards and five touchdowns on the ground in his first season.
Neither can equal Riddick in terms of receiving, though.
Given the team's depth at the position, Denver can play to Riddick's strengths without asking him to shoulder too much of the rushing burden.
His arrival could put Devontae Booker's future with the Broncos in jeopardy. The team's leading rusher (612 yards) in 2016, Booker has seen his stock slowly decline over the past two seasons.
Denver would save $720,000 and absorb $95,848 in dead money if it were to cut the fourth-year back, according to Over the Cap.
