Why the Vikings should be cautious
While Theo Riddick has had a solid career, he is coming off of a slow season. 2018 was his first campaign without a touchdown since entering the league and his 555 total yards were his lowest since 2014.
The Vikings would have to find room to bring in a potentially declining running back entering his seventh season.
Despite being a dominant receiving back, Riddick is not nearly as big of a threat on the ground as he has averaged just 170.5 yards rushing per season. His career-high in rushing yards is 357 back in 2016 and he has never rushed for more yards than he has received in a single season.
Defenses will be able to narrow down what the offense is planning when Riddick is on the field. He will not expose defenses or break a long run. Riddick is a very solid player who has a defined role in the offense.
The Vikings have weapons aplenty on the offensive side of the ball. Mike Zimmer wants to run the ball more in 2019, but Dalvin Cook has to stay on the field.
Signing Riddick would be a move made more for the passing game than the rushing attack. With a third-round pick invested in rookie Alexander Mattison, the Vikings may not want to spend more resources at the position.
In my opinion, Riddick is too good of a playmaker to not make an offer. Depth is crucial for a championship run and adding more skill players on offense simply cannot hurt.
