With the Bears having won two straight and three of their last four games, there's a different vibe at Halas Hall.

"You can just feel confidence," said coach Matt Eberflus. "The guys have always been confident in their approach and confident in their abilities. But you can see the feeling of confidence when you actually see it, the progress, when you see the result. You can certainly feel that with the players and the staff.

"The guys are upbeat, and they've always been that way. But you can certainly feel the confidence growing as we start stacking these wins."

In their last two games, the Bears defeated a pair of division rivals who had winning records in the Vikings and the Lions.

After Sunday's convincing 28-13 win over Detroit, center Lucas Patrick told ChicagoBears.com that he felt the locker room at Halas Hall last week was closer than it's been all season. He reiterated those remarks Monday to reporters.

"It's been amazing," Patrick said. "We were talking yesterday after the game; this is probably the best week I've seen this locker room in a long time. You could just tell that there was a confidence and like a calm confidence.

"The other cool part if there's a lot of across-the-locker room talk. It's just fun when we're walking around, and you can see guys mingling. This team is pretty close right now. You kind of build over the season, and relationships build. It's a credit to the importance 'Flus' has put on that since the spring. All we've put into that, I think we're seeing a lot of that come to fruition now."

The Bears hope to carry the momentum they've created into the final four games of the regular season, beginning Sunday when they visit the Browns in Cleveland.

"Three-and-one in the last month; guys can feel that," Eberflus said. "And it's really a credit to them in terms of their practice habits and what they've been doing all along with their positive attitude, and then being close and having that tight-knit group in the locker room."

After failing to hold a 26-14 fourth-quarter lead in an eventual 31-26 loss to the Lions Nov. 19 in Detroit, the Bears finished strong in their back-to-back wins. Justin Fields completed a 36-yard pass to DJ Moore to set up Cairo Santos' 30-yard field goal with :10 remaining to beat the Vikings 12-10. And then the Bears outscored the Lions 18-0 in the second half to erase a 13-10 halftime deficit in Sunday's victory.

"I love winning, and especially for the team," said safety Jaquan Brisker. "I love seeing everybody happy in the building, from the staff members to the players to whoever it may be."

The Bears defense has shown marked improvement in key aspects of the game such as generating takeaways, registering sacks, stopping the run and getting off the field on third down.

"The chemistry's getting better, and guys want to see guys succeed," Brisker said. "There's no selfishness on the defense, and you can tell. From the front to the back end, everybody wants to make plays."

Brisker credits Eberflus with helping the Bears improve.

"You can tell just by the way the locker room is reacting these last couple of weeks," Brisker said. "It hasn't always been great, but guys have been wanting to come into work and wanting to grind and wanting to turn this thing around. Like I've been saying these last couple weeks, the players that we brought in and the coaching staff and things like that have done a great job these last couple weeks of keeping us together."
