A few news and notes from Friday’s second practice:
— Raiders owner Al Davis watched his first practice of training camp, accompanied through much of it by his son Mark.
Davis talked briefly with Robert Gallery, rehabbing from an offseason appendectomy, and spoke with George and Josh Atkinson, the twin sons of former Raiders defensive back George Atkinson and star sprinters and football players at Livermore’s Granada High School.
— Drills were supposed to be at three-quarters speed, but the Raiders second team defense was apparently coming up short of that at one point in the eyes of defensive coordinator John Marshall.
“You guys are going to stay second group for the rest of your (bleeping) life,” Marshall said. “You’re going through the motions. Grow the hell up.”
— More emphasis on teaching _ quarterbacks coach Paul Hackett has quarterbacks JaMarcus Russell, Jeff Garcia, Bruce Gradkowski and Charlie Frye line up in a row in front of them where he spends a few minutes quizzing each on protections and routes.
— Jonathan Compas, an undrafted free agent guard from U.C. Davis, was getting reps as a third team center.
— Erik Pears, the free agent tackle/guard signed as a free agent, jumped offside during one drill.
— The second-team offensive line during one sequence consisted of left tackle Khalif Barnes, left guard Chris Morris, center John Wade, right guard Marcus Johnson and right tackle James Marten.
— Hiram Eugene spent some time with the second-team defense, with Michael Huff working with the first team at free safety.
— Rather than music during stretching as in the Lane Kiffin regime, the Raiders get a running dialogue from strength and conditioning coach Brad Roll.
“We’re bringing in the smokers tonight. You name it, we’re smoking him,” Roll said of the post-practice meal.
“Stretch those quads _ a happy quad makes a happy hamstring,” Roll said.
— Four more “learning intensive” practices before the hitting begins on Monday . . .
