They're the plays that shaped this year's postseason.

The manufacturer of the helmet that Chiefs quarterback Patrick Mahomes shattered during their AFC wild-card game with Miami says it “did its job” by protecting him on a helmet-to-helmet collision Saturday night.

Tua Tagovailoa maintained his scorching form since his return from a concussion, throwing three touchdown passes as the Miami Dolphins beat the Cleveland Browns 39-17 for their fourth straight win.

The Chiefs overcame a 10-point deficit and four turnovers Sunday to clinch their fifth consecutive AFC West title by beating Miami 33-27. But he threw for 393 yards and two scores to help the Chiefs (12-1) earn their eighth consecutive victory. It was the Chiefs’ second consecutive comeback at Hard Rock Stadium, where they won the Super Bowl in February despite Mahomes' two interceptions. He threw an interception, bobbled a snap and took the big sack to set up the Dolphins’ first touchdown.

The Chargers and Falcons are tied at 17 midway through the fourth quarter. Kenny Moore also starred for the Colts with a spectacular one-handed, diving end-zone interception in the second quarter. Adams didn’t do much other than run the scrambling Darnold to the sideline midway through the second quarter. Seattle took its opening possession and got 19-yard touchdown pass from Russell Wilson to Freddie Swain. Mack also recovered a Duke Johnson fumble in the first quarter and deflected a Watson pass in the second quarter.

Tua Tagovailoa had help from a less-heralded rookie while Justin Herbert struggled against a relentless pass rush, and the surprising Dolphins earned their fifth consecutive victory by beating the Los Angeles Chargers 29-21 Sunday. The Chargers could never catch up after they were hurt by two mistakes in the kicking game that allowed Miami to take a 14-0 lead. “I was disappointed in the special teams and some of the things that went on there. “It changed the momentum.”SPECIALMost lopsided of all was the special teams matchup. Jakeem Grant, the NFL leader in punt return yards, helped the Dolphins’ field position with three runbacks for 57 yards.

The 22-year-old Tagovailoa was on the winning end of an action-packed duel with Arizona quarterback Kyler Murray, who finished with 283 yards and three touchdowns. Tagovailoa was much more productive in his second start after throwing for just 93 yards against the Rams last week. BIG FOOTSanders made a 56-yard field goal as time expired in the second quarter to give the Dolphins a 24-17 halftime lead. INJURIESDolphins: WR Preston Williams (foot) left the game in the second quarter and didn't return. Cardinals: CB Kevin Peterson left the game early in the second quarter for a concussion evaluation and didn't return.

He entertained those along the bench by dancing after the Miami Dolphins' first touchdown, and greeted 5-foot-6 Jakeem Grant with a leaping chest bump to the face mask after another score. The early 33-yard scoring drive was the Dolphins' longest, as the big lead allowed them to keep Tagovailoa mostly under wraps. We tried to make him see a lot of different things, and for the most part it worked.”The Rams' defense received little support from their offense, though. “We heard a lot about the Rams' defense," Miami safety Eric Rowe said, “but they had to worry about our defense.”INJURIESTwo-time Rams Pro Bowl cornerback Jalen Ramsey became ill before the game and didn’t play.
