OAKLAND, Calif. -- The Oakland Raiders played their starters for three series, bleeding into the second quarter, on both sides of the ball. Charles Woodson Jerseys While the offense, particularly quarterback Derek Carr, looked crisp, the defense was burned to a crisp ... other than reigning NFL defensive player of the year Khalil Mack.

It was a good tuneup for both sides, though you have to wonder how much the Raiders will subject their front-line players Derek Carr Jerseys to potential injury in the next two exhibition games, even if the defense needs major tinkering as the Raiders fell to 0-2 with the 24-21 loss to the Rams.

QB depth chart: Taking the field against live action for the first time since suffering a broken right fibula on Christmas Eve, Carr was sharp. Khalil Mack Jerseys In three series, he completed 7 of 9 passes for 100 yards and two touchdowns with an interception on a play when Michael Crabtree stopped running his route. Carr threw a couple of deep jump balls to Amari Cooper -- with Cooper making an acrobatic move for a completion on one throw, Rams defensive back Kevin Peterson knocking down the other.

When it was starters vs. starters, the Raiders looked ...: Offensively, the Raiders looked ready for Week 1 at the Tennessee Titans. Latavius Murray Jerseys Defensively? Not so much. Derek Carr & Co. looked like a fine-tuned machine, even as left tackle Donald Penn's holdout continues and Marshall Newhouse continues to settle in at the position. Cooper, as mentioned above, made a ridiculous catch down the right sideline and Crabtree juked Troy Hill on his 13-yard TD catch and run.

One reason to be concerned: Yeah, the defense. Amari Cooper Jerseys Rookie middle linebacker Marquel Lee again looked overmatched too many times for comfort -- even if he is a fifth-round draft pick. Cornerback TJ Carrie, who again started at right cornerback ahead of Sean Smith, had a rough go of it, too. Smith, who is facing assault and battery charges, could potentially miss time, and first-round draft pick Gareon Conley has not practiced since minicamp in June because of a leg issue. A lot of things need to be cleaned up on this side of the ball. Imagine the issues if Mack -- who had a sack, three QB pressures, four tackles (two for a loss) in three series -- was not on the team.
