David Helman brings the Chiefs up from fifth to fourth in his Week 17 power rankings, pointing to a nearly flawless record against projected playoff teams.

Brian Thomas Jr. became the first rookie wideout to cross the 1,000 mark, as he hauled in nine passes for 132 yards and a score in the win. Tank Bigsby found the end zone on one of his 12 carries, and the defense held the Raiders to only 314 total yards of offense.

The Miami Dolphins are finally back to .500 for the first time since September after back-to-back wins moved the team to 8-8 with one week left to play. They need an unlikely Kansas City Chiefs win in Week 18 to have a shot at the playoffs,
