Now that we’ve seen Mitchell Trubisky play four games under Matt Nagy’s tutelage, it’s time to examine how he’s doing. We’ve seen him play 269 snaps and throw 130 passes, and while that’s still a fairly small sample size, it’s big enough that we can begin to analyze how he’s performing in a variety of situations.
Growth Through Each “Quarter”
Last offseason I looked at Trubisky’s performance in 4-game snapshots, borrowing the idea of breaking an NFL season down into quarters from Lovie Smith. There I found that Trubisky got progressively better in every “quarter.” Since Trubisky has played 4 games this year, he now has 16 in his career, giving him a full 4 “quarters” that we can track. Let’s take a look.
Well that looks pretty good. I said last offseason that, statistically speaking, Trubisky needed to throw more TDs while keeping everything else the same. Here we see that he has managed to throw more TDs, and everything else has stayed the same or improved. That’s good growth to see from a 2nd year QB.
Of course, four games is a small sample size, and this doesn’t look quite as rosy if we remove the Tampa game from the equation. Then his yards per attempt drops to 5.7, TD percentage to 1.9%, and his INT % (2.9%) and sack % (8.0%) both rise a bit higher than they were late in his rookie year.
Through three weeks, the stats suggested Trubisky was actually playing worse than late in his rookie year. That’s not entirely surprising given that learning a new offense often results in a step back at first.
Adding the TB game in there makes this look good, but now the question is whether the TB game was an aberration or a sign of things to come.
