In what was arguably the best game of the year in the NFL, the Kansas City Chiefs defeated the Los Angeles Chargers 34-28 in overtime. The game had some of everything. There were four different goal line stands, big plays from defense, turnovers, and 35 points in the 4th quarter and overtime.

Entering the game Thursday night, the Chiefs division lead was tentative. The Chargers had already beaten them earlier in the season and could have wrestled the division lead away. But Patrick Mahomes, Tyreek Hill and Travis Kelce had other plans.

Here are the 4 key takeaways from Thursday nights electric win for the Chiefs.

Chiefs Week 15 Takeaways from win over Chargers

4. Travis Kelce is easily one of the greatest tight ends in NFL history

Stephen Curry has revolutionized basketball forever. He has changed the game and the position that he plays. Well, I believe Travis Kelce is doing the same thing to the tight end position in football.

Don't get me wrong, I am not saying that Kelce is the greatest tight end in history. But he is amongst the greats.

He is, however, changing the way the position is perceived and the type of athletes that play it. Most people have Rob Gronkowski, Tony Gonzalez, Shannon Sharpe and Antonio Gates in a class themselves. But unlike any of those players, Kelce is faster and more agile than any we have ever seen. Did you see what he did to end last night's game?

Travis Kelce is a 6-time Pro Bowler, 3-time first team All Pro with a Super Bowl championship to his credit. He is only playing in his 8th season but already ranks 6th all-time in receiving yards for a tight end with over 8,900. He is less than 100 yards behind Gronkowski and has played about half the games as the other players on this list.

But it's not just his statistics that make him stand out. Since he came into the league, we have seen a revolution of tight ends who run faster and look more like receivers. George Kittle burst onto the scene with similar skill sets. This year, the Atlanta Falcons drafted Kyle Pitts. If you have watched Pitts play, you would think you were watching a wide receiver.

The position, along with the game, is changing. Kelce is a big part of that change.

3. Patrick Mahomes and the Chiefs offense got their swagger back

The Chiefs offense and especially Patrick Mahomes had struggled for a large chunk of this season. Mahomes was among the league leaders in turning the ball over. Even though he once again turned it over twice in Thursday's win, the offense found their rhythm again.

Mahomes threw for 410 yards and three touchdowns. Tyreek Hill reeled in 12 catches for 148 yards and a receiving touchdown and Travis Kelce had a whopping 10 catches for 191 yards and the walk-off touchdown. When it mattered most, the stars came to play. The last three Chiefs drives were all 75-yard touchdown drives.

Mahomes in three of the last five games has 10 touchdown passes. After the game, he spoke about that swagger that the team is now getting back.

2. The Chiefs defense came up big when it mattered

A lot of the talk recently had been about how the Chiefs defense was carrying the team during Mahomes' struggles. That is a fair point to make. They had only allowed 65 points total over the course of their previous six games, all wins.

Justin Herbert and the Los Angeles Chargers offense was the biggest test during this stretch. Kansas City's defense gave up plenty of yards, and Herbert hit some big throws against the Chiefs secondary. But in some of the game's biggest moments, the Chiefs defense won the day.

The Chargers had three different goal to go occasions inside the Chiefs 5-yard-line and came away with zero points.

They weren't blunders by the Chargers, but rather great plays from good players. You could argue the play of the game was the final play of the first half. Chiefs safety Daniel Sorensen stepped in front of Herbert's pass to the end zone and knocked it down. On the others, they defensed another pass and stripped the ball from Chargers running back Joshua Kelly.

The Chiefs defense is becoming a play-making defense, led by Sorensen.

1. Kansas City is the favorite for the #1 seed in the AFC

With the win, the Chiefs improved to 10-4 and essentially locked up the AFC West division. Now, they can set their sights on the only first round bye going to the top seed of the conference.

The Tennessee Titans and New England Patriots both have better conference records. New England almost assuredly will finish with a better record in the AFC. So, in order for the Chiefs to get the #1 seed, they might need the best record to themselves.

Well, the schedule favors the Chiefs. New England is an underdog this weekend at the Indianapolis Colts and still have to play the Buffalo Bills again. The Titans offense is looking worse as every week passes and is not a lock to win any of their remaining games. Even Baltimore faces some tough tests and Lamar Jackson might not even suit up against Green Bay Sunday.

All of that heavily favors the Chiefs to claiming the bye.
