BOURBONNAIS — Free agency was yet another humbling experience for star-crossed linebacker Aaron Lynch this year. Hoping for a multiyear contract after re-establishing himself as a productive NFL player in 2018 — and still only 26 — he instead settled for a one-year, $1.45 million contract to return to the Bears.

Disappointed?

‘‘Yes and no,’’ Lynch said. ‘‘I hit the market when a bunch of other dudes hit the market, too. You’ve always got a Tier 1 guy and a Tier 2 guy. I was in the middle of that: ‘Well, if we can get this guy, then we don’t need him.’

‘‘[But] for me and my family, as a football player to grow more, this was the best place. Obviously, who doesn’t want a long-term deal? So I’m disappointed in not getting a long-term deal with a lot of money, but I’m also super-happy that I got to stay in Chicago. And even though I’m taking what I’m taking, mentally I didn’t want to be anywhere else.’’

It was a tough break for Lynch but a good one for the Bears. He is still a superior athlete at 6-6 and 270 pounds, with big-play potential playing behind starting outside linebackers Khalil Mack and Leonard Floyd.

‘‘[He] worked his tail off last year, coming into our program to understand how we do things with this culture, and he’s productive,’’ coach Matt Nagy said. ‘‘He understands learning from Khalil and Leonard and those guys. It’s important to have depth, and we like where he’s at.’’

Lynch indeed has bought in to the defensive culture instilled by Nagy and former coordinator Vic Fangio.

‘‘I just want to succeed on every play I [get],’’ Lynch said. ‘‘It doesn’t matter of it’s two plays or 30, 40, 60 plays a game. If I go in for Khalil, you know that y’all aren’t going to be missing anybody. That’s what I want to be.

‘‘I want to build up the guys around me and make sure that our rotation is the same. Khalil’s a freak of nature. Leonard’s a freak of nature. We’re all freaks of nature. But [with] those two guys, you have to step up your game. That’s what I want to do this year: Make sure that whether I’m starting or not that I can be the best I can be.’’

That’s a mindset even Lynch admitted he wouldn’t have had when he entered the NFL.

‘‘No,’’ he said. ‘‘Because five years ago, it was all about me: ‘I’m going to make the most plays I want to make.’ [Now] I’d rather be on the No. 1 defense than excel [individually]. Don’t get me wrong, I want 13 sacks. But if I’m on the best defense and get five sacks, then I’m doing my part.’’

Lynch knows he has work to do to improve on his 2018 performance. After missing virtually all of training camp and the preseason because of a hamstring injury, he had three sacks and an interception in 13 games. He missed the final two games of the regular season and the wild-card playoff loss to the Eagles with an elbow injury.

‘‘I had a pretty decent year, [but] I could have done way freakin’ better,’’ Lynch said. ‘‘I could have stayed a little more healthy and taken care of myself a little more. But it was cool.

‘‘We have a huge opportunity this year, so I just want to be better than I was last year. If a lucrative deal comes, who gives a [darn]. But I’m hoping I stay here for a long time.’’
