"I think he's been outstanding," Del Rio said, via the San Francisco Chronicle. "He comes in, had a tremendous career and is very humble. Obviously he is intelligent. He asks good questions. He's got arm talent. It's a matter of getting familiar (with) what we do and how we do it ...
Cook wasn't satisfied with his play early in the weekend sessions, pointing to several flubs and the difficulty getting on page with receivers in a new scheme.
McGloin hung onto the clipboard holder role in Oakland last year, but Cook should be given every chance this preseason to wrangle the backup gig.
A solid start in rookie camp is the first step.
Some other nuggets from rookie camps around the NFL:
"Don't trust all those reports out there," Del Rio said. "We felt pretty good about our reports. He looked terrific. He's very athletic. He's a serious guy and intelligent guy. We're excited about him."
» While Ward was on the field, first-round safety Karl Joseph didn't practice as he continues to rehab from a knee injury. Joseph should be on the field by training camp.
"I guess if we did do something it would be later on. But right now we're set," Rivera said Saturday, via the Charlotte Observer. "We're very happy with what we've seen the last two practices with the young guys."
Defensive coordinator Vic Fangio isn't worried so much about Floyd's weight. Fangio said the rookie -- listed at 244 pounds -- will play between 230 and 235 pounds this season. The DC is more concerned with the speed Floyd adds than the size he lacks.
"We wanted speed," Fangio said, via the Chicago Sun-Times. "Our team speed up front last year was below average. To add somebody with some speed as part of his toolbox is something we were intrigued by."
If Langford's blocking and receiving don't improve, Howard could become the Bears passing-down back in a full-fledged committee.
» The Redskinsare working rookie Su'a Cravens at inside linebacker during camp. If all works out as planned, Cravens will become a new member of the ever-increasing hybrid linebacker/safety gang.
"He has some growing to do, but he did some outstanding things today as well,'' Jackson said after the first rookie camp practice, via the Cleveland Plain Dealer.
"It's just about learning both sides, then I can plug in anywhere if something happens - and it just gives me a head start on learning the offense," Conklin said, via the Tennessean. "If I know what the right tackle is doing and what the left tackle is doing, I'll be able to understand the whole scheme better."
»Jaguars receiver Allen Hurns, who underwent sports hernia surgery in January, was cleared for full activities and joined his teammates for individual drills, per the Florida Times-Union. With Hurns on track to be fully healthy in an ascending offense, the Jags could be one of the most explosive teams in the NFL in 2016.
