The have been here before.In fact, they were here last year.Well, not here in Las Vegas, but here in the Super Bowl. They won it last season in Phoenix, besting the by a score of 38-35. Kansas City now has a chance to win back-to-back championships, becoming the first team since the 2003 and 2004 to do so.All that stands in their way is Charles Woodson Jersey a familiar opponent: the .ADVERTISEMENT The Chiefs beat the Niners in Super Bowl LIV. But that was four years ago. These teams are completely different save for a couple of key individuals.Andy Reid, and .They hold the key to winning this Sunday.Kansas City has appeared in four of the past five Super Bowls, and so have those key three. This has become an almost annual tradition and it shows. On Opening Night of , the Chiefs looked comfortable, handling the chaos with a calm that only experience can provide.By contrast, the 49ers had a bit of nervous energy. It's been four years since they were here and they came up short that time.Reid and Mahomes together in the postseason is a hard duo to bet against. Despite this not being the type of regular season fans have come to expect from the Chiefs they went 11-6 Kansas City found another gear in the postseason like they always do. It took a while to figure out how Las Vegas Raiders Jersey to make it work with an average receiver corps that had the most drops in the NFL of any team. It took a bit for a second-year running back in to come on consistently. It took some time for Reid to evolve his system yet again to fit what his roster could do.But it happened, and the Chiefs are right back in the big game.Mahomes (not Purdy) named checkdown king ahead of Super Bowl LVIII The key now is for Reid, Mahomes and Kelce to be themselves.They've had two weeks to prepare for this game.

They can also take the ball away, tying for the most interceptions in the league with 22.

Pa ses between the two don't show up on a call sheet. A lot of the time, it's just Mahomes evading pre sure long enough to let Kelce find an open space on the field. Mahomes is K.J. Wright Jersey acutely aware of Kelce's positioning at all times. As a defensive back tasked with guarding the 6-foot-5 Kelce, you can't predict which route he's running based on his release oftentimes, Kelce isn't even running a route found on the route tree. It makes it hard, as a result, to know what leverage to take on him.Former NFL linebacker Luke Kuechly Nick Wright says Chiefs offense will have Darren Waller Jersey its best game in months Kelce has three receiving touchdowns so far this postseason. He had just five in the regular season. It's further evidence Mahomes, Kelce and even Reid tap into something different in the playoffs.To win against the Niners (again), that's all they'll have to do.Let Mahomes and Kelce be Mahomes and Kelce.And let Andy Reid cook.Carmen Vitali covers the NFC North for FOX Sports.
