Tarik Cohen followed up a solid rookie campaign with a really good sophomore season in 2018. Despite playing less than half of the available offensive snaps and getting fewer than 100 carries and 200 total touches, he finished with 1,169 yards from scrimmage, scored 8 touchdowns, and was one of the most explosive players in the NFL. For good measure, he was also a 1st team All Pro as a punt returner after leading the NFL in punt return yards and finishing 5th in yards per return.
Despite all of this, I think Cohen’s limited snaps and touches keep people from appreciating just how valuable he is to the offense. Cohen’s diminutive stature keeps him from being a conventional lead running back, but he still has a substantial impact on offensive production.
And there are actual numbers to back it up. The graph below shows the relationship between the total number of touches (carries or pass targets) that Cohen gets and how many points the offense scores. In order to account for different numbers of snaps in games, I looked at Cohen touches out of total snaps for that game. So if he got 10 carries + targets and the offense played 20 snaps, 50% of the plays went to Cohen.
There’s a pretty clear trend where the offense scores more points when more plays run through Cohen. We see that anecdotally as well, as the Bears scored 27 or more offensive points all 5 times Cohen was involved in 14+ plays in a game, and only 1 time in the other 12 games (including playoffs). An R2 value of 0.65 gives a strong number to support this correlation (a value of 0 would mean there is no relationship, while 1 would mean the relationship is perfectly linear).
