Theo Riddick

One of the mid-aughts' most impactful receiving backs, Riddick registered at least 50 receptions in four consecutive seasons from 2015-18 with the Lions, posting a career-high 80 (with 697 receiving yards) in 2015. He set career highs in carries (92) and yards (357) the following year in just 10 appearances. Although he closed his career in two short stints with the Broncos and Raiders, Riddick will always be remembered as a member of Detroit's organization.

The move comes the same day the Raiders added Kenyan Drake. Riddick's deal includes only $50,000 guaranteed, so he will be far from assured of maintaining his spot on the 53-man roster. Headed into his age-30 season, Riddick is a deep reserve/special teamer only at this stage of his career. 

The Raiders have been placing players on the COVID-19 list more than just about every team in the league. Riddick will need multiple days of negative testing to be activated. Devontae Booker has filled in as Josh Jacobs' passing-game sidekick.

Riddick being made inactive likely bodes well for Josh Jacobs' health. Jacobs went into Week 9 dealing with a knee injury and gave up a surprising amount of carries to Devontae Booker. Not having Miller or RT Trent Brown among other injuries on the offensive line may have a negative effect on Jacobs but his path to RB1 status remains through volume.
