No. 2 Mitch Trubisky
Last season, Trubisky was expected to make a big jump. The team was certainly relying on him to be one of the five best players on the roster. According to his 2019 ranking, he took that step. Trubisky saw steps forward in touchdowns, completion rate, yards per attempt, pretty much every stat. And these are on a per throw basis, and it is not because he started his rookie season behind Mike Glennon.
Yes, Trubisky also made your heart race. He bolted out of pockets and lost yards before picking up more. He threw passes that made you hold your breath or yell out in disgust before watching it fall harmlessly to the ground.
In his second NFL season, his first as in a Matt Nagy offense, Trubisky showed room for progression. This is no shock. However, it is not farfetched to assume that his progression is realistic next season. Look for another strong season from Trubisky, as he tries to build off of year two in the NFL.
