OAKLAND, Calif. -- Browns free safety Damarious Randall knew it the moment Baker Mayfield entered the Browns facility for the first time.

"He's just got his own swagger about himself, like he could have the whole team, the whole city, the whole state of Ohio behind him,'' said Randall, who spent the previous three years playing with Aaron Rodgers in Green Bay.

Randall sometimes shakes his head at the plays Mayfield makes in practice.

"I know he seems like he's a kid, but he's going in there and throwing passes that you see 10-year vets probably can't even throw and it's just crazy to try to wrap your mind around it,'' he said. "A lot of people wanted us to take Sam Darnold or another QB in the draft, but I've always been like 'in (GM John) Dorsey we trust,' because his track record speaks for itself.

"I'm sure he's the one that drafted Patrick Mahomes (in Kansas City) and look at Patrick Mahomes. He's lighting it up. I feel like we're in good, good hands and I just hope this team can stay healthy and the sky's the limit for this team.''

Randall has seen firsthand Mayfield's Pied Piper effect.

"He sees everybody the same. He can talk with just about anybody about anything," he said. "He plays video games, he can dance, he can do it all. I haven't seen that in a long time in this league, a guy that has so much swagger and just like by the way he carries himself. You can tell that it's effortless and he really don't try to be an outcast."

As Mayfield prepares to make his first NFL start Sunday in Oakland, where he'll becomes the 30th quarterback to start a game for the Browns since 1999, here's what some of his teammates are saying about him:

In Schobert's experience, rookie QBs don't trash talk a defense the way Mayfield did while rallying the Browns from 14 points down to beat the Jets.

"Every young or rookie quarterback I've ever played against is trying to just get their mind right and figure out what they're going to do for the next play and trying to read the defense,'' he said. "You don't really get a lot of that from young guys, so it's definitely something that I haven't experienced. [It shows] his competitive fire, and the kind of person he is and the edge he brings to the football field."

His first impressions of Mayfield in practice?

"He's just an ultra competitor,'' said Schobert. "He came in from day one slinging the ball around, trying to make plays and obviously if he made a mistake or the defense got a play on him he came back and tried to make us look foolish the next play. You could see from day one he was a great guy to have around our locker room and leading the team."

Schobert has marveled at Mayfield's arm strength.

"He can really whip the ball in there and make some throws across the field with velocity that maybe defenders aren't seeing day in and day out which makes it harder to catch and harder to make a play on the ball,'' he said. "He's a little bit of a gunslinger. But a lot of great quarterbacks have been there and he's kind of in the mold. If he keeps progressing, he's going to be great for us.''

Seven of Landry's eight catches came from Mayfield against the Jets, including a few where he was tightly covered.

"One thing I know about him: he walk it like he talk it,'' said Landry. "That's something that I appreciate and respect about him and he's continued to do."

Landry, who's starting to develop chemistry with Mayfield, noted, "he definitely has that attitude and charisma, and that is contagious."

Landry, who dropped a short pass near the goal-line against the Jets, is still adjusting to Mayfield's fastball.

"I try to catch as many balls from him every day, just trying to get that feel for it, but it's definitely an adjustment,'' he said.

Like offensive coordinator Todd Haley, Johnson was impressed with Mayfield's debut, but not ready to sculpt the bronze bust just yet.

"Yeah, he definitely commanded the huddle as a quarterback typically does regardless of what year you are,'' he said. "That really doesn't matter. I think his performance is what showed more than anything that he's different than the previous rookie quarterbacks that we have had. But I still think it's one game, or really a half, so he's still got a lot more to show and a lot more to prove."

Kirksey watched from the sidelines with a shoulder and ankle injury as Mayfield guided the Browns to 21 points and give the Browns their first victory in 20 games and 635 days. In Oakland, he'll be back out there trying to support Mayfield with more turnovers and maybe even a defensive score.

"Baker, he's a guy that comes out every day willing to work,'' Kirksey said. "He comes in early. He's trying to become a student of the game. He has what it takes to win ball games. We saw that Thursday night with the throws that he made. Tyrod (Taylor) is the same way. Tyrod is a leader. With him, he has helped Baker a lot. Drew (Stanton) has helped Baker a lot.

"That quarterback room is definitely one of our bright spots on this team. We are [good] behind center. I believe they can get the job done. I believe that we have three good quarterbacks that can play."

Garrett, who's tied for the NFL lead with four sacks, hopes more Mayfield translates to more offense.

"He can just give us more energy by being on the field more,'' said Garrett. "Having more time of possession for us helps us as a defense recovering and even more time to look at our mistakes and how we can correct those and hopefully get them to pass the ball more, hold the ball more and get takeaways.

Browns cornerback Carrie spent the past four seasons in Oakland with quarterback Derek Carr, and sees some similarities between him and Mayfield.

"The one thing that I continue to harp on about Derek Carr is his work ethic and that's something that you see in Baker,'' said Carrie. "He's staying after practice and trying to make sure he's getting throws in on lunch breaks, just doing little niche things here and there that you wouldn't expect a rookie to do. He's really come in and developed as a pro pretty early.''

Carrie has also been impressed with Mayfield in practice, where he was running the show team for the starting defense before last week.

"He's got a very strong arm coming in as a rookie, and he understands the game and he's been able to pick up on the offense very well and really able to dissect our defense in some areas that would normally give certain quarterbacks trouble,'' said Carrie. "So from that standpoint he's really good in just figuring out where his throws need to go and where his reads are, which is pretty impressive for a rookie quarterback.''
