After a bonkers Week 3, it seemed as if everything leveled out in Week 4 in fantasy football (and the NFL at large).

All of the Bills came back to earth, most of the Patriots went back to being productive and the Buccaneers stopped looking like a record-breaking offense.

Once again, I’m here to parse through the noise and break down the rookies that are contributing to the mess that’s been the first four weeks of the season. Here are three first-year players whose stock went up this week, and three whose stock fell.

Stock up

Sony Michel (RB – NE)
Michel seemed like the odd man out in New England during the first three weeks of the season. He was averaging just 3.5 yards per carry during his first two games of the season (Weeks 2 and 3) while sitting behind Rex Burkhead and James White.

With Burkhead out for the year due to a neck injury, Michel suddenly became the Patriots’ featured back. He carried the ball 25 times on Sunday in a blowout win, racking up 112 yards and scoring a touchdown.

White still seems to be the third-down guy for the Pats (Michel wasn’t targeted once in the passing game), but Michel seems to be the main runner – he was on the field for 88 percent of New England’s offensive snaps.

Miami’s defense has struggled to defend the run all year – Michel was the third rusher to surpass 100 yards against the Dolphins this season – but it certainly seems like the rookie out of Georgia is an RB2 going forward in all leagues.

Nick Chubb (RB – CLE)
Michel’s running mate at Georgia, Chubb, also had a breakout game Sunday against the Raiders. He only had three carries, but he took two of them to the house and finished the game with 105 yards.

The problem is, it’s still impossible to tell how Chubb will factor into Cleveland’s offense going forward. Despite his monster game Sunday, Chubb still has only been on the field for 4.5 percent of the Browns’ offensive snaps, according to Pro-Football-Reference.com, while Carlos Hyde has taken more than 57 percent of snaps at running back. Hyde hasn’t been a slouch, either, scoring at least one touchdown in every game this year.

Mary Kay Cabot of the Cleveland Plain Dealer reports that Chubb will see more touches, however, after his two big runs.

He’s worth a speculative add in most leagues at this point. Cleveland’s offensive floor is much higher with Baker Mayfield under center than Tyrod Taylor, and Hyde has been injury-prone throughout his career.

Calvin Ridley (WR – ATL)
I feel sorry for anyone who followed my advice after Week 1 and dumped Ridley.

The Alabama product is on a record-setting pace. His six touchdowns through four games are the most of any player in his first four career games in the history of the league. Obviously, he’s not going to keep up the pace of 1.5 touchdowns per game, but it’s encouraging to see that Matt Ryan is using him more and more.

Ridley is now owned in more than 80 percent of Yahoo and ESPN leagues, so it’s unlikely that he is on the waiver wire in your league, but if you managed to scoop him up after Weeks 2 or 3, congratulations.

Stock Down

Most rookie quarterbacks
I am more than happy to be patient with all of the quarterbacks who were drafted in the first round of this year’s draft (especially when talking about their long-term NFL success). But for fantasy relevance this year, Baker Mayfield may be the only one you should be using in a pinch or two-quarterback leagues.

Despite his turnovers, Mayfield still threw for nearly 300 yards and two touchdowns and would have had a better day had his receivers not dropped a few key passes.

Meanwhile, Josh Rosen, Josh Allen and Sam Darnold all threw for less than 200 yards and combined for just two touchdowns. Allen had the worst outing by far, posting a terrible 36.3 rating against the Packers’ average defense.

Darnold looked like he could be a fantasy backup after his Week 1 performance against the Lions, but that seems to be more about the Lions’ ineptitude than anything at this point. Stay away from all three of these guys – and continue to watch Mayfield’s numbers before making a move for him.

Ronald Jones II (RB – TB)
Jones finally got his shot to play in Week 4 after being inactive for the first three games, but he failed to do anything that would convince the Bucs’ coaches that he should be getting more touches.

He averaged just 2.9 yards per carry and caught one pass, losing a yard on the play. He still out-touched Peyton Barber 11-8, and he could be the No. 1 back in Tampa coming out of the team’s Week 5 bye, but owners don’t have much to be pleased about at this time.

Antonio Callaway (WR – CLE)
While his teammate, Nick Chubb, stole the spotlight Sunday, Callaway may have played himself out of some snaps in Week 4.

Callaway still has an excellent chance to cement himself as the No. 2 receiver in Cleveland, but owners may want to look for other options in Week 5. The talented rookie out of Florida hauled in only three of his seven targets against the Raiders, including a two-point conversion after one of Chubb’s touchdowns.

His other lowlight was early on in the game when he slipped out on a route and tipped a pass from Mayfield to a Raiders defender, who returned it for a touchdown. Callaway slipped often during the game, which can partly be chalked up to the Raiders’ sub-par playing surface. But head coach Hue Jackson wasn’t impressed and said Callaway “may not [be] playing as many plays,” according to the Plain-Dealer.

If you have Callaway on your roster, it’s certainly worth keeping him, as he has game-breaking speed that gives him tons of upside, but you may want to sit him this week.
