Former Bears coach Lovie Smith always talked about breaking the NFL season down into quarters, which splits a 16-game season into 4-game sample sizes. I’ve always thought that was a good way to look at it, as grouping four games together helps smooth some of the statistical noise of individual good or bad games.
With that in mind, I want to track Mitchell Trubisky’s rookie season through the quarters lens. Trubisky sat out the first quarter of the season, but took every offensive snap for each of the last three quarters. Let’s see how he progressed through those.
First, I want to point out that Trubisky was tasked with doing more in each quarter.
In his first 4 games, Trubisky had the ball in his hands on only 26.5 plays per game. Coaches tried to minimize what he had to do, which was why more plays featured handoffs and fewer featured him ending the play with a pass attempt, sack, or run.
In Trubisky’s 5th-8th games, that number increased to 34.3 plays per game, and it took another jump to 39.8 plays per game in the last four games.
For the 32 qualified passers in the NFL this year (224 or more pass attempts), the mean and median were both 38.2 pass attempts, meaning Trubisky was being given as much responsibility (in terms of plays per game) as an average quarterback by the end of the season. This clearly shows that coaches were willing to put more responsibility on Trubisky’s shoulders as the season wore on, which is a good sign.
