The 29-year-old was plagued by drops and not performing when his team needed it the most. But on the biggest play of the season, Valdes-Scantling came up with a circus catch to seal KC's trip to its fourth Super Bowl in five seasons. The Chiefs faced third-and-9 from their 46-yard line while leading the Baltimore Ravens 17-10 with 2:19 remaining in the fourth quarter. Patrick Mahomes dropped back and floated a ball deep downfield to Valdes-Scantling. MVS stumbled and fell backwards but managed to bring in the ball while on his back at Baltimore's 22-yard line. It was an unbelievable play. Check it out:MVS IN A BIG SPOT.📺: #KC…
