Fantasy football sizzlers, fizzlers: Josh Jacobs, Miles Sanders hit the ground running in Week 4

The nature of the NFL season is a series of ebbs and flows. There are good weeks and bad weeks. But just when you think a particular player may have worn out his welcome in one place, one big game could change the picture dramatically.

That might be the case for a couple of fourth-year running backs who set career highs in rushing yards on Sunday.

These players saw their fantasy values increase or decrease most based on their performances in Week 4:

Sizzlers

RB Josh Jacobs, Las Vegas Raiders: The Raiders have nothing to lose by riding Jacobs, who's likely in his final season in Vegas. The rub is, Jacobs is starting to show he may be worth a big-money deal, racking up 175 total yards and a pair of touchdowns vs. Denver.

RB Miles Sanders, Philadelphia Eagles: Sanders filled the bell cow role, rushing 27 times, scoring twice and totaling 156 yards from scrimmage.

RB Austin Ekeler, Los Angeles Chargers: He's been relatively quiet so far, given his early average draft position, but a three-TD performance against Houston was a gentle reminder that Ekeler can still explode for huge games.

RB Rashaad Penny, Seattle Seahawks: Looking much like he did at the end of last season, Penny ran wild with 151 yards on the ground and two touchdowns in a high-scoring affair.

TE T.J. Hockenson, Detroit Lions: In the shootout vs. Seattle, Hockenson erupted for eight catches, 179 receiving yards and two touchdowns. Even though starting wideouts Amon-Ra St. Brown and D.J. Chark didn't play, Hockenson showed he can be a go-to receiver as well.

Fizzlers

RB Travis Etienne, Jacksonville Jaguars: To be fair, backfield mate James Robinson didn't fare any better but Etienne was quiet again with just 32 rushing yards and no contributions in the receiving game.

WR Chase Claypool, Pittsburgh Steelers: The 6-4 Claypool was targeted just twice against the Jets, catching neither pass. Not even a quarterback change seems likely to get him back on track.

WR Julio Jones, Tampa Bay Buccaneers: The Bucs' ailing receivers are slowly getting healthy, but the lost time has put Jones firmly behind WR3 Russell Gage in the pecking order.

WR Rashod Bateman, Baltimore Ravens: What's most troublesome for Bateman is that he's been targeted often (22 times in four games) but only has 11 receptions. That's not a stat that instills confidence.

WR Jarvis Landry, New Orleans Saints: Landry appears to be fading out of the New Orleans offense, as each week has been quieter than the last. His latest effort: two targets, two catches, 7 yards.
