The Kansas City Chiefs defeated the Pittsburgh Steelers 29-10 Wednesday to not only reach 15-1 on the season, but clinch the top seed in the AFC and get a first round bye and home field advantage in the playoffs.

Mahomes, who was 29-of-38 for 320 yards and three touchdowns, says three games in eleven days shows a lot of toughness from the team.

 Mahomes has a high ankle sprain; defensive tackle Chris Jones didn't play in Pittsburgh because of a strained calf, and the Chiefs hope to get offensive tackle D.J. Humphries back in time for the postseason.

The 19-point margin of victory was the largest of the season for the Chiefs. Even without Jones, Steelers quarterback Russell Wilson was sacked five times, intercepted once, and forced a Pittsburgh fumble.

Mahomes was encouraged by the offense, with Hollywood Brown and rookie Xavier Worthy combining for 12 catches for 125 yards and a touchdown against the Steelers. Mahomes says the offense is peaking at the right time.

 Tight end Travis Kelce had eight catches, and his 12-yard scoring catch in the fourth quarter set a team record for career touchdown receptions with 77.

 The Chiefs have one regular-season game left; it's against the Broncos in Denver. No word on how many starters will actually play.
