: Outdoor practice fields: Helmets and shortsSaturday's practice was the second of this preseason camp for the Oregon football team, and thus under NCAA acclimation rules the Ducks still weren't wearing any pads.That didn't stop the offense and defense from getting physical with each other at times, including a 7-on-7 run-game drill in which everybody but the receivers and defensive backs is on the field. The playcalling is predictable, and the outcome comes down to one thing: which side dominates the line of scrimmage.With the first-team on the field Saturday, senior running backbroke free for a couple long gains, behind an offensive line that returns four starters. But with the twos on the field, the offense found yards tougher to come by.Within the first few reps by the twos, redshirt freshmanelicited praise twice from defensive line coach. When Aumavae stopped a third running play, and the second in two reps, Salave'a couldn't contain his excitement: "Man, Popo's out here eatin', baby!"Among UO coach's biggest goals for this preseason camp, he said before it began, was shoring up depth up front defensively. A team can never have too many quality defensive lineman, Cristobal said. From the looks of it Saturday, Aumavae has the makings of one for the Ducks.A native of Stockton, Calif., Aumavae was a three-star recruit rated a top-50 player in the state of California, and a top-50 defensive tackle in the nation for 2017. But he arrived at Oregon nursing injuries to both shoulders, the recovery from which sidelined Aumavae for the entirety of his redshirt year."I was able to pick up on the plays and the schemes, all that," he said. "Other than that, it was frustrating."As of this spring, Aumavae was finally suiting up and participating in practices with the Ducks. He's lost weight but feels stronger after a summer in the weight room, and clearly has impressed Salave'a already this preseason."It's crazy," Aumavae said of being back in action. "It's kind of hard to put into words. I love football, and it's great to be back out here."Aumavae said his conditioning could still improve, as camp progresses. And Salave'a is constantly encouraging him to employ more "violent throws," when he's working to shed a blocker.But already, Aumavae is looking like a player who can spell starting nose guardat times, allowingandto focus on matching up with guards and tackles at one of the defense's end positions."It's great, just being able to get back out there and kind of get back to where I was — if not better, thanks to coach Feld and his strength and conditioning," Aumavae said.: While that run-game drill was going on, the receivers and secondary matched up in a passing drill highlighted by freshman safetyinterception. … Walk-on corner(above) also forced a turnover, in 1-on-1 pass drills, ripping the ball out as receivertried to secure a pass from. … Herbert did complete long touchdown passes toandduring that drill.
