It hasn’t taken long for first-round pick and former Alabama wideout Amari Cooper to make an impression on his newest teammate, Oakland Raiders quarterback Derek Carr.

Carr’s brother, David, who now works as a football analyst after 11 NFL seasons, says Cooper’s ability — at least in the early going — is the best he’s seen in some time. The former No. 1 pick in the 2002 draft has been around several great wide receivers during his stint in the league and believes Cooper will be a comparable weapon.

“He’s an unbelievable player. I can’t wait until August,” David Carr said in an interview with 120Sports.com. “There’s ten yards of separation on some of these routes, which is unheard of in the NFL.”

Offseason training activities (better known as OTAs to football fans) have begun and Cooper has flourished during the passing skeleton and 7-on-7 portions, according to reports.

In need of a playmaker to complement Carr in the passing game, the Raiders selected college football’s Biletnikoff winner in May after Cooper posted the best single-season in program history at Alabama. Speed and route-running are considered strengths and Cooper hasn’t disappointed thus far.

“If you are an Amari Cooper fan, go out and buy the jersey because I’m seeing some routes this kid’s running, and it’s unbelievable the separation he’s getting,” Carr said. “I understand it’s OTAs and it’s early, but he is so crisp in and out of his cuts… you gotta see this guy on film.”

NFL.com reported Thursday that Oakland is tinkering with the idea of putting Cooper on special teams as a kick returner.

“Amari Cooper is another guy we’re working back there,” according to Raiders special teams coordinator Brad Seely. “It depends on, you know, what exactly his role is on this football team if he’s going to do some of that stuff. He could because he’s got a lot of talent. At this time of the year, you’re really just trying to evaluate as many guys as you can.”
