Derek Carr taking advantage of Raiders’ receiver depth

ALAMEDA - Raiders coach Jack Del Rio says the recipe for a good quarterback comes down to two things: decision-making and accuracy.

Derek Carr has already shown significant progress in both areas, along with an increased willingness to throw the deep pass.

The second-year quarterback is coming off back-to-back 300-yard games in which he threw touchdowns to four different receivers while completing 64 percent of his passes. Carr’s quarterback rating of 102.4 is also the seventh-highest in the NFL, better than that of Russell Wilson, Peyton Manning and Andrew Luck.

Wide receiver Andre Holmes credits Carr’s willingness to spread the ball around for the team’s early success.

“The offense is built so that’s there’s multiple options on every play,” Holmes said Tuesday. “Most offenses are like that but we’re just executing really well and finding our third read. DC’s doing a great job of finding the open man due to his progression.”

Carr has already completed passes to 13 different receivers. First-round pick Amari Cooper and veteran Michael Crabtree have garnered the most attention but backups like Holmes and Seth Roberts are also making an impact.

A second-round pick a year ago, Oakland’s quarterback has shown his biggest improvement under pressure.

According to ProFootballFocus.com, Carr has completed 73 percent of his passes (14 of 19) for 243 yards and two touchdowns when opposing defenses blitz. That works out to a quarterback rating of 150.7.

“He makes good decisions and he is accurate passing the football,” Del Rio said. “We just want to continue to grow that.”
