Despite Kolton Miller‘s struggles last season https://www.raiderslockerroom.com/authentic-derek-carr-jersey , Jon Gruden still believes in his left tackle. In fact, he believes in Miller so much that the Raiders coach made a big prediction.“We think Kolton Miller’s going to be one of the best at left tackle in football,” Gruden said, via Scott Bair of NBCSportsBayArea.com. “He’s not only healthy, he’s in great shape. He’s gotten a lot stronger. He’s added some weight, some muscle. And he’s still a real flexible athlete that can run and change direction and being in the second year in the system we expect a lot of good things.”Miller, the 15th overall pick in 2018, allowed an NFL-high 16 sacks and a league-worse 65 pressures, per Bair. Miller dealt with multiple knee sprains but refused to blame injuries for the rough start to his NFL career.But Miller added that being healthy this season “will help tremendously.”Miller, who now weighs 328 after weighing 310 at the 2018 Combine, will stay at left tackle with free agent signee Trent Brown moving to right tackle.“It felt good staying left [tackle],” Miller said. “But, of course, I’m a team player. I’m going to go where they put me and what they think is best for the team. I know that I have a job to do and I know last year wasn’t good enough. There was a lot of problems with that and I’m expected to be better, and I will be better.” The Oakland Raiders practiced at an off-site facility for a second consecutive day Friday as thick smoke from California's deadly wildfires blanketed the Bay Area.Much like they did a year ago when similar conditions arose due to fires in Northern California Derek Carr Jersey White , players and coaches were bused to an indoor gym at the former Alameda Naval Air Station for practices Thursday and Friday.Although the Raiders were forced to scale back their workouts as a result, coach Jon Gruden was mostly pleased with how things went under the circumstances."It's like an indoor ice rink that was transformed into a soccer field," Gruden said. "We didn't have much room to get the splits and get the routes but I'm not going to make any excuses. We're not the only people dealing with adversity right now. It was either that or get nothing so I'm really pleased with the players, the coaches and the preparation that we were able to get in."Smoke has filled the sky in Northern California for more than a week and the air quality has been at dangerously unhealthy levels in recent days.The Raiders will get a break from the conditions with road games each of the next two weeks. They play Sunday in Arizona and are in Baltimore to face the Ravens on Nov. 25."We have to deal with what we have to deal with," Gruden said. "We got a lot of reps in. We are confident that they know what to do. We just have to trust that they'll go out there and perform at the highest level possible." Offensive coordinator Greg Olson said that the fires have helped keep things in perspective."Our hearts go out to all the people who lost lives and property, and certainly to all the first responders." Olson said. "For us, yeah, we are missing a practice. We are missing the ability to go outside, but for other people it's changing their lives or has changed their lives. Nobody here on this team has lost lives or property, so we are fortunate in that regard."Right guard Gabe Jackson has tried to remain indoors as much as possible to avoid the smoke-filled air."From being here to going home I haven't spent much time outside," Jackson said. "You're always concerned about what's going on around you, especially the people that's affected, but at the same time you have to do what you have to do."Notes: Wide receivers Jordy Nelson (knee) and Martavis Bryant (knee) did not practice and are out for Sunday's game. . Cornerback Gareon Conley (groin) is questionable.
