(LAKE FOREST, IL) – Chicago Bears quarterback Mitchell Trubisky delivered a message to his critics Friday. On a video call with Chicago media, Trubisky said he is just trying to prove everybody wrong and prove his teammates right. Trubisky, 25, is set to compete in training camp with veteran Nick Foles for the Bears' starting job. The second overall pick of the 2017 NFL draft had been Chicago's unquestioned starter for most of the past three seasons, but his play regressed last year. Trubisky finished 28th in total QBR (39.4), tied for 27th in touchdown passes (17), 21st in passing yards (3,138), 32nd in yards gained per pass attempt (6.1) and 28th in traditional quarterback rating (83.0) as the Bears went 8-8 and missed the playoffs. In 2018, Matt Nagy's first season as coach, the Bears went 12-4 as Trubisky passed for 3,223 yards, 24 touchdowns and 12 interceptions and rushed for 421 yards and three touchdowns. Chicago acquired Foles from the Jacksonville Jaguars at the onset of the new league year and declared an open quarterback competition. The organization later declined Trubisky's fifth-year option. Foles, the MVP of Super Bowl LII while with the Philadelphia Eagles, enters camp with a slight disadvantage of not having worked on-field with any new teammates in the offseason. But Foles, 31, arrives in Chicago with strong pre-existing relationships with several of Chicago's current offensive coaches, including Nagy, who spent time with Foles in Philadelphia and Kansas City before landing the Bears' top job. Both quarterbacks were inside the Bears' facility Friday and participated in a walkthrough with the club's rookies.
