Kenneth Walker III goes back to Seattle on Sunday night leading the NFL in rushing for the unbeaten Chiefs

Kenneth Walker III was the Seattle Seahawks' Super Bowl MVP. On Sunday night he comes back to Lumen Field with the Kansas City Chiefs, who are 5-0, and he leads the NFL with 133 rushing yards per game, according to the Associated Press. Kickoff is 8:20 p.m. ET on NBC.

Walker signed with Kansas City as a free agent in the offseason. He ran for 128 yards and two touchdowns in last week's 22-6 win over the Chargers, his fourth 100-yard game of the season, and has eight total touchdowns. Seattle's run game has slipped without him. The Seahawks average 107.2 rushing yards a game, 18th in the league, the AP said.

"We're happy for him, but also, we're trying to figure out ways to stop this guy, too," Seattle coach Mike Macdonald said. Andy Reid doesn't expect Walker to make it personal. "He kind of has one speed: He's coming at you," the Chiefs coach said. "It doesn't matter who he's playing or where he's playing."

Seattle may get some help of its own. Zach Charbonnet, who tore his ACL in January and missed the first six games on the physically unable to perform list, was added to the active roster Thursday, and Macdonald said there is a possibility he plays. Rookie Jadarian Price is out with a chest and shoulder injury. Rashee Rice is out for Kansas City, per ESPN's injury report.

Here is the RANT angle. The defending champions are 3-3 and lost 17-14 to Denver last Thursday, and the oddsmakers still have them favored by 2.5 over an unbeaten team. That says a lot about how little the market trusts this 5-0 start, or how much it trusts Seattle's pass defense, which leads the league at 141.3 passing yards allowed per game. If Walker runs through the team that let him walk, that line is going to look silly.

Patrick Mahomes picked up his 100th career regular-season win against the Chargers. Jaxon Smith-Njigba leads the league with 717 receiving yards for Seattle.
