Jay Cutler says wide receiver Roy Williams, who signed with the team this month, is still learning. Williams worked with Chicago offensive coordinator Mike Martz in Detroit, but Cutler says this system is different. Cutler expects Williams to be "right where we need him" when the regular season opens on Sept. 11 at Soldier Field. Williams agreed, saying, "everybody wants us to click right now, but it's going to take a little time." "He's figuring stuff out. Missing those days of training camp kind of hurt him, set him back a little bit," Cutler said. "But you can just tell he's thinking. We do things a little bit different from Detroit, and obviously Dallas. There are just little nuances in our offense and little details you can see [that] he's still processing and thinking through."
