Derek Carr has been making up time with two rookie targets the Oakland Raiders hope he connects with often in the next several years.

The Raiders' rookies and quarterbacks were among the players to start work earlier this week at their Napa, California, training camp. The first full-team practice is Friday morning. As the entire team reported for camp Thursday, receiver Amari Cooper (first round) and tight Clive Walford (third round) spoke about catching up with Carr.

Carr, a second-round pick who was the only rookie quarterback to start all 16 games last season, missed a big portion of the offseason workouts with a finger issue. He did participate in the mandatory June minicamp and held his own personal camp in Bakersfield recently.

Cooper believes the timing with Carr is coming along well as the Raiders begin camp in earnest. Cooper said the plan is to build chemistry daily in camp.

"Just to get some time with him, he hasn't really been practicing when I first got to OTAs, so I wanted to build a rapport with him," said Cooper, who was the No. 4 overall pick out of Alabama. "It was beneficial because we got a couple of days to throw. He is very accurate with the football."

Like Cooper, Walford is expected to get immediate playing time. He is encouraged by what he has seen from Carr.

"He goes out there with a lot of confidence, makes great throws," Walford said. "You don't really see him miss throws. You can't really tell that he was missing."
