Chiefs QB Mahomes shows off potential

Denver Broncos: The Broncos didn't sign Case Keenum with three-interception outings in mind, but coach Vance Joseph was impressed with his new quarterback in the opener, all things considered. "After the interceptions, he had his best drives, so that speaks to his confidence," Joseph said Wednesday. "I was really impressed with Case on the sideline -- he didn't go in the tank at all, he kept his teammates going and obviously moved the ball for us after the mistakes." Keenum kept firing and finished with 329 passing yards (8.4 yards per attempt) and three scores, including the game-winner. "No matter what's happened, we're still in the game, we're going to run our offense, we're going to be in attack mode," Keenum said.

Kansas City Chiefs: It's safe to say the Patrick Mahomes show got off to a strong start, as the second-year quarterback was named AFC Offensive Player of the Week on Wednesday after going 15 of 27 for 256 yards and four scores against the Los Angeles Chargers in Week 1. Even after the blistering start, coach Andy Reid says his pupil is just scratching the surface of what he can ultimately be. "Plenty of room to grow," Reid told reporters of Mahomes. "A ton of room to grow. And he knows it and he just attacks it. He has a unique personality. And everything is not going to be roses. He is a young guy. But if he keeps that attitude, he is going to be fine."

Los Angeles Chargers: The Chargers' defense finished third in scoring defense (17.0 points per game) last season while allowing just one opponent to reach 30 points in a game, which might be why coach Anthony Lynn isn't panicking the team after allowing 38 in Week 1. "No, our defense is fine," Lynn said when asked about possibly changing things up. "Everybody's got to execute and do their job. Gus Bradley's a fine defensive coach. We've got a great defensive staff, so we're not going to change anything up on that defense." It would sure help to get defensive end Joey Bosa back, but he appears unlikely to return soon as he prepares to see a specialist regarding his foot injury.

Oakland Raiders: Oakland's roster churned more than any in the league this offseason under Jon Gruden, and that continued after Week 1, with the team adding defensive tackles Johnathan Hankins and Clinton McDonald while bringing back wideout Martavis Bryant, who was among the team's final cuts just four months after being acquired for a third-round pick. Asked why the team brought Bryant back, Gruden said he thinks the receiver is "in a good place right now" after struggling with illness and injuries during camp. "I think he's healthy, I think he's ready to go," Gruden added. "I'm sold on that. We've been in contact with him since he's been away, and as I said when we made the trade to get him when he's right, he can be a difference-maker."
