Understanding the Role of Newly-Acquired Free Agents in 2019: Offense

| March 20th, 2019

The Bears have made a number of moves in free agency, and I want to use some statistics to weigh in on their likely role on the roster / value to the team. Let’s start with a look at the offense.

Mike Davis

Davis has just 238 carries in 4 seasons so it was a little surprising to see the Bears move so quickly to sign him at the start of free agency. But a closer look reveals why they did so.

A few weeks ago I identified the typical physical profile of a running back in this offense, and Davis fits the bill, as you can see in the table below. Thresholds that he failed to hit are highlighted in red.

Davis matches the profile of backs who are usually targeted for this offense. He’s short but well built and has solid acceleration (as evidenced by the first 10 yards of the 40-yard dash) and explosion (as evidenced by the jumps). This doesn’t mean he’ll magically be a stud here after being a role player in San Francisco and Seattle, but it explains a little bit about why he was on the Bears’ radar.

Another way Davis fits is in terms of his skill set. Running backs in this offense are asked to do two things: run between the tackles and catch the ball out of the backfield. The table below shows how effective Davis was doing those compared to Jordan Howard in 2018, with both compared to Kareem Hunt as an ideal (on-field) back for this system. I highlighted cells in red when one running back stood out from the other two in a bad way, and green when one running back stood out in a good way.

A few thoughts:

  • The first thing that stands out is that Davis is better than Howard at running between the tackles, where both were asked to have a majority of their carries in 2018. This can be evidenced by his significantly higher yards/carry average between the tackles last year, when he was comparable to Kareem Hunt in that regard. It’s worth noting that this trend was only really true in 2018; Davis was generally inefficient at pretty much everything prior to that in his career, and Howard had -by far – the worst year of his career in 2018. Still, the Bears are banking on getting the 2018 form of Davis, which would be a running upgrade over 2018 Howard.
  • Sticking with running, let’s take a look at success rates in the bottom two rows. This was one area where I pointed out Howard actually did quite well, and Davis did as well (again in 2018, not so much before that). Since success rate is a measure of staying with or ahead of the chains, this indicates Davis should hopefully be able to continue Howard’s success converting in short-yardage situations.
