Mitch Trubisky's tenure in Chicago since being the second overall pick of the 2017 NFL draft hasn't been great. It hasn't been terrible, either. It's been a blend of good and bad which has led to an incomplete picture of who he is as a quarterback entering his fourth year in the league. It's the main reason why the Bears traded for Nick Foles; Trubisky can't be trusted (yet) to be the unquestioned starter for a team that on paper has playoff potential.
The fact that Trubisky can't be trusted contributes to the narrative that he's the team's biggest liability. Even if he wins the Bears' quarterback competition, will he really have the unconditional confidence of his coaches and teammates? Will Bears fans have the kind of faith in Trubisky that fans of other contenders have in their quarterbacks? Probably not. There's no reason why they should. Trubisky hasn't been consistent enough through nearly three seasons as a starter to deserve that level of trust.
According to a recent breakdown of every team's biggest liability, it was Trubisky, of course, who took the title for the Bears.
If new Chicago Bears quarterback Nick Foles can beat out Mitchell Trubisky and play well in 2020, the Bears might be a playoff team. If he cannot, Chicago might be looking at a lost season.
While the Bears roster is very talented, Trubisky has been anything but a steady presence under center. He has struggled to push the ball down the field—he averaged just 6.1 yards per attempt in 2019—and has limited what head coach Matt Nagy is able—or perhaps, willing—to do on offense.
Chicago ranked 29th in passing yardage last year and declined Trubisky's fifth-year option this offseason.
If the Bears are again one-dimensional, they're going to find it difficult to be relevant in the tough NFC North.
I ran a poll on Twitter that asked Bears fans who they prefer as the starting quarterback with just over one month to go before the season kicks off. The results were predictably close, but the nod went to Foles (56%). It feels safe to assume a big reason why fans hope Foles ends up QB1 is because of his proven track record in big moments. Even if he's a boring player with a limited regular-season ceiling, he has ice in his veins during the game's biggest moments. He's steady. He's consistent. He's pretty much the anti-Trubisky.
Is it fair to say Trubisky is a liability? Of course, it is. If he fails, the Bears will be set back for several seasons. Even if Foles salvages the team's short-term outlook, the long-term success of the franchise depends on Trubisky living up to his scouting report and becoming a franchise quarterback. And there just isn't enough evidence to prove he's capable of doing that.
If we don't know by now whether Trubisky can turn the corner and be a top-tier starting quarterback in the NFL, it's probably safe to say he can't.
