The Bears have made a number of offensive improvements this offseason, but Jay Cutler is still concerned about the team's line. "The offensive line is definitely going to be a concern, seeing where those guys fit in, and seeing what five we go with," Cutler said. "If Gabe (Carimi) comes back (from knee surgery), if J'Marcus (Webb) pans out, Chris Williams, where are we going to put him at? "There are some question marks there. Until we really get that resolved and get our front five settled in, we have some work to do on the offense." Since joining the Bears before the 2009 season, Cutler has been sacked 110 times in 41 regular-season games.
