Kansas City finally clinched its third consecutive AFC West title and the No. 1 seed in the playoffs, Sunday, with a 35-3 pounding of the Raiders. Patrick Mahomes threw for 281 yards, highlighted by a 67-yard TD pass to Tyreek Hill and an 89-yard TD toss to Demarcus Robinson for the 12-4 Chiefs. That gave the first-year starter 5,097 yards and 50 touchdown passes, joining Peyton Manning as the only QBs to hit 5,000 and 50 in the same season.

Hill finished with five catches for 101 yards, becoming the Chiefs’ single-season leader for yards receiving with 1,479, while adding a fourth-quarter touchdown run. Damien Williams added 51 yards and a score on the ground as the Chiefs beat the Raiders for the eighth time in nine games.

The Chiefs’ Travis Kelce had five catches for 62 yards, giving him 1,336 yards this season. That broke the NFL record for tight ends set by the Patriots’ Rob Gronkowski in 2011, only for the 49ers’ George Kittle to pass him a few minutes later.

Mahomes was 14 of 24, giving him a franchise-record 383 completions this season. He began the day tied with Trent Green with 369. Coach Andy Reid broke a tie with former Chiefs coach Marty Schottenheimer for seventh on the NFL’s career wins list with his 206th.
