The Kansas City Chiefs won a thriller on Sunday as quarterback Patrick Mahomes led a 13-play, game-winning drive in the contest's closing seconds to edge the Detroit Lions.

The Chiefs are now one of just three undefeated teams in the NFL, joining the New England Patriots (4-0) and San Francisco 49ers (3-0) as the only squads remaining with an unblemished record.

Kansas City owns a two-game lead in the AFC West with a quarter of the season now in the books, and once again, the Chiefs maintained their high standing in the various "power rankings" from around the web.

NFL.com slotted the Chiefs in at No. 2 this week behind New England following Sunday's victory. Here's a portion of what analyst Dan Hanzus had to say about the Chiefs:

"…Mahomes made magic when it mattered most for the undefeated Chiefs. Down 30-27 and facing a fourth-and-8 with less than two minutes to play, Mahomes scrambled 15 yards to move the chains. Darrel Williams would cap a 13-play, 79-yard drive with a 1-yard touchdown plunge. Meanwhile, the decision by Chiefs corner Bashaud Breeland to scoop up a loose football at his own goal line and run it back 100 yards the other way for an uncontested touchdown will serve as a teaching tool for offensive and defensive coaches going forward…"

Kansas City checked in at No. 2 in ESPN's rankings as well, trailing only the Patriots. The folks at Sports Illustrated, meanwhile, ranked the Chiefs as the top team in the NFL this week, jumping New England.

Here's what the Monday Morning Quarterback Staff had to say about the Chiefs taking over the No. 1 spot:

"Chiefs vault Patriots for first time this season, thanks to quality of wins and opposition. K.C. and New England could jockey at the top of these rankings until they actually play on Dec. 8."
