Sometimes the NFL's top plays on a Sunday come from people we wouldn't expect. They're the plays that make you ask, "Who was that?" These performances can change a player's career.
Here's a look at Week 10's unheralded ballers, starting with a quarterback who continues to the defy the odds and hold off his more well-known teammates:
Case Keenum, QB, Minnesota Vikings
Threw for 304 yards and a season-high 4 TDs in 38-30 victory over Redskins
What happened: Emotions were running high as Teddy Bridgewater was active for the first time in two seasons but Keenum stole the show, torching Washington's defense with deep ball after deep ball.
Why it matters: The Vikings continue to prove they are among the NFC contenders with Keenum at quarterback. Keenum is going to make it hard to bench him for Bridgewater. This is a guy who signed a one-year, $2 million deal in late March. He'll get paid a lot more next March.
Nevin Lawson, CB, Detroit Lions
44-yard fumble return for a TD in 38-24 win over Browns
What happened: Lawson survived what he called the worst quarter of his career, giving up a big reception and missing a tackle that led to a TD. He rebounded by forcing a fumble from Browns tight end Seth DeValve, scooping up the ball and running it to the crib.
Why it mattered: The TD put the Lions up 17-10 after they had fallen into an early 10-0 hole against the Browns. The Lions will need consistent play from Lawson to stay in the NFC playoff hunt. Lawson is in a contract year so this should help his bank account.
Dion Jordan, DE, Seattle Seahawks
Sack and three QB hits in 22-16 win over Cardinals
What happened: In his first game since 2014, Jordan made a big splash, notching a sack and applying consistent pressure in just 33 defensive snaps. Jordan showed flashes of why he was drafted No. 3 overall in 2013.
Why it matters: We all know who Jordan is, but we probably know him for his suspensions or for being waived after failing a physical rather than for what he can do on the field. This is a big step along his redemption tour to change that perception. Let's hope he succeeds.
Maurice Harris, WR, Washington Redskins
One-handed, 36-yard TD catch in 38-30 loss to Vikings
What happened: Harris was called up to the active roster on Saturday after impressing everyone throughout practice. He finished with two catches for 50 yards and showed big-play ability, fighting off Vikings CB Trae Waynes to make an acrobatic, one-handed TD grab.
Why it matters: In Harris' first game of the season, he played more snaps than free-agent bust Terrelle Pryor. Washington continues to seek contributing playmakers for Kirk Cousins so Harris will get more opportunities.
Corey Grant, RB, Jacksonville Jaguars
56-yard TD run off fake punt in 20-17 OT win over Chargers
What happened: Grant took the direct snap on fourth-and-7 late in the first quarter, broke a couple of tackles, wove through defenders and scored a TD to put the Jaguars up 7-0.
Why it matters: Another week, another Jaguars special-teams touchdown. It's the second consecutive "Who was that?!" appearance for a Jaguars special-teamer. This team keeps finding ways to win, primarily due to an elite defense.
