"(Trubisky) has been really, really good in the fact that he's taken this head-on," Bears head coach Matt Nagy said Monday, according to Kevin Patra of NFL.com. "He's accepted it. He understands it. We're all so competitive, but we're human, too.
"There is a realness to the fact that, 'OK, you're going to bring somebody else in here and have me compete' - initially it's probably a shock. But then after that, it's like, 'Let's go.'"
The Bears acquired Nick Foles early in the offseason to challenge Trubisky, who regressed in his third pro season. The former No. 2 overall pick threw for 3,138 yards with 17 touchdowns and 10 interceptions in 2019, averaging a career-low 6.1 yards per pass attempt.
Chicago also declined the fifth-year option on Trubisky's contract, allowing the 25-year-old to become a free agent after the 2020 campaign.
"We're going to have competition throughout our entire team," Nagy said. "There are other competitions going on right now. Obviously, this is the focal point, and these guys have been great. I'm excited to see how it goes when we get to training camp, and we get to the preseason games and then to the season.
"They'll both handle it really well. Again, when you're honest with people, it makes things in life so much easier. These guys are competitors, and they're good people. They're going to make it work."
Foles, a former Super Bowl MVP, spent last season with the Jacksonville Jaguars.
