Trestman points to fundamentals for Cutler in wake of Bears' loss to Lions

Chicago Bears coach Marc Trestman had no major problem with Jay Cutler's decisions. His fundamentals were another issue.

Cutler threw three interceptions, lost a fumble and the Bears fell for the first time under Trestman with their 40-32 loss in Detroit on Sunday. With Drew Brees and the New Orleans Saints coming in this week, Chicago (3-1) can't afford a letdown from anyone, let alone their quarterback.

Against the Lions, they were outplayed in just about every area. The defense gave up 139 yards rushing to Reggie Bush. Special teams struggled, but Cutler stood out for all the wrong reasons.

Trestman hopes the fundamental breakdowns were an aberration for Cutler. He also realizes it could happen again, but the Bears are "working to prevent" that.
