Coach Lovie Smith conceded that the Bears had reservations about using Kahlil Bell as their No. 2 running back due to ball security issues. For now, Matt Forte is the Bears' starter and Michael Bush is No. 2. "We're concerned," Smith said of Bell. "Kahlil can't fumble the ball that much, as well as he played, especially in that Green Bay game. He put the ball on the ground twice. You can't do that." Bell had three fumbles on 79 carries last year.
