There were no surprises for Amari Cooper on the first day of rookie minicamp Friday.

“It went like I thought it would go,” the Raiders’ first-round pick said. “I made a couple of plays.”

That he did, as he and big tight end Clive Walford, Oakland’s third-round pick, stood out as they are supposed to in a field of 10 draft picks, 14 undrafted free agents and two dozen nameless players.

“He was fine,” Raiders head coach Jack Del Rio said, after asking if he had to give daily updates on Cooper. “He is going to be a good player.”

Fans, who haven’t had a 1,000-yard receiver in 10 years, and former players are screaming from the rooftops about Cooper.

Former Raiders receiver Fred Biletnikoff, who led the team in receiving from 1968 through ’73, said “it’s unbelievable” that Oakland added not only Cooper but also former 49ers receiver Michael Crabtree. That’s two Biletnikoff Award winners — given to the top receiver in college football.

“The quarterback is in a great spot now where he knows when the ball leaves his hand that the receiver is going to catch the ball,” Biletnikoff said in a phone interview. “It’s a great confidence booster. Derek (Carr) doesn’t have to be right on target, just get the ball around them.”

Cooper was ready to go Friday after signing his four-year, $22.7 million contract — with a $14.7 million signing bonus — Thursday.
