Who was that?! Unheralded ballers who made a difference in Week 10

We all know the NFL stars who generate SportsCenter highlights on a regular basis. Every week, though, some performances make us say, "Who was that?"

It could be the undrafted rookie receiver who catches a long touchdown pass, the backup quarterback who piles up stats or the journeyman linebacker who seals a win with a big play.

This is for them. Take a look at Week 10's unheralded ballers, starting with a quite unexpected QB-to-WR duo who lit up the field for the Bills. Yes, those Bills:

Matt Barkley, QB, Buffalo Bills

15-of-25 for 232 yards, 2 TDs and 0 INTs in 41-10 win over Jets

Why it matters: Because it's Barkley, a guy who is on his sixth NFL team and wasn't on a NFL roster two weeks ago, destroying a once-respected Jets defense with help from LeSean McCoy and the Bills' run game. It took injuries of Josh Allen and Derek Anderson along with incredible struggles from Nathan Peterman to get Barkley his first start in two years, and he played a better game than any of them have all year. Barkley might not get a chance to follow up on his performance, but he gave Bills fans something to cheer about Sunday.

Robert Foster, WR, Buffalo Bills

Three catches for 105 yards in 41-10 win over the Jets

Why it matters: Foster became the first Bills player in more than a year to get 100 receiving yards in a game. Fresh off the practice squad, Foster caught a 47-yard pass from Barkley on the first play of the game. He also had a 43-yard catch. He joined Keelan Cole and Allen Hurns as the only undrafted rookies in the past five seasons to record a 100-yard game. Foster had just 389 receiving yards in his four seasons at Alabama.

Raven Greene, S, Green Bay Packers

Sack, 26-yard fake punt conversion in 31-12 win over the Dolphins

Why it matters: Greene had played only special teams before Sunday, but the undrafted rookie took advantage of his first opportunity on defense, playing 30 snaps and contributing a sack. He also had a 26-yard run on a fake punt. After Green Bay moved on from Ha Ha Clinton-Dix in a trade late last month, Greene moved up on the depth chart.

Darius Jennings, returner, Tennessee Titans

58-yard kickoff return on first play of the game in 34-10 win over Patriots

Why it matters: Jennings made the first big Titans splash in their beatdown of the Patriots by taking the opening kickoff to the Patriots' 40-yard line. It set up a Tennessee opening-drive touchdown and we quickly saw a team that wasn't going to back down against New England.

Leonte Carroo, WR, Miami Dolphins

Recovered a blocked punt, recovered a fumble and had a 14-yard fake punt conversion in 31-12 loss to the Packers

Why it matters: Carroo had the trifecta Sunday, making an impact on the Dolphins' three biggest special-teams plays of the day. His two recoveries led to half of the Dolphins' points. Carroo, a 2016 third-round pick, spent most of the season on the Dolphins' practice squad before being called up recently after the Dolphins' rash of injuries. Carroo also had a 20-yard catch and could see a bigger offensive role with Albert Wilson and DeVante Parker battling injuries.

Ryan Anderson, LB, Washington

Forced fumble in 16-3 win over the Bucs

Why it matters: With Washington holding on to a 16-3 fourth quarter lead on its heels with the Bucs driving into the red zone, Anderson punched the ball free from Jacquizz Rodgers, forcing a turnover and helping preserve the win. Anderson, a 2017 second-round pick, is a backup linebacker but he made a starter impact Sunday. Washington has a two-game NFC East lead, and looks like the favorite to win the division right now.
