The Bears have failed to score before halftime on four occasions this season and have been out-scored 106-60 during their current three-game losing streak.
"There are some positions on the team that need to step up with leadership and things like that around the club," Bennett said, according to the Chicago Sun-Times. "But overall, I just feel like we need passion to come from certain places. I don’t think the passion is always there all the time. But overall, it just hasn’t been there."
Bennett declined to specify which players he feels are lacking passion, saying only it was "several people."
Quarterback Jay Cutler leads the NFL with 18 interceptions thrown and the team is tied for third in the league in turnovers lost.
The Bears are 5-9 and in fourth place in the NFC North. Chicago hosts the Detroit Lions on Sunday.
