Each week Des Bieler breaks down the NFL’s slate to identify key fantasy factors on which to focus when the Sunday action gets underway.

Saints at Steelers

The Steelers are returning from a bye, and Ben Roethlisberger owners are anxiously hoping he returns to looking more like the guy who threw 12 touchdown passes in Weeks 8 and 9, as opposed the guy who followed that up with just two in Weeks 10 and 11. The Saints are 23rd in pass defense.

Browns at Bills

Jordan Cameron has been practicing again with Cleveland, after missing several games with a concussion. Owners who have been using another TE during this time probably should wait a week to see how things develop, but Cameron could be very useful at a weak position in the fantasy playoffs.

Texans at Titans

Here’s hoping that Arian Foster owners have had Alfred Blue to plug in while the Texans’ star RB has been out with a groin injury. But Blue has proven to be a decidedly inferior talent, averaging 3.6 yards per carry with no touchdowns. Foster (5.1 YPC, seven TDs) appears to be on track to play this week.

Giants at Jaguars

In the wake of Allen Robinson’s season-ending injury, Cecil Shorts appeared to be set for steady production. However, the WR caught just one pass last week for three yards, as rookie QB Blake Bortles continued to struggle severely. If Bortles keeps circling the drain, he could submerge Shorts’s value.

Bengals at Buccaneers

Giovani Bernard came back from a three-game absence due to hip and shoulder injuries, but not only did he not displace Jeremy Hill, he may have convinced Cincy coaches to feature Hill more. Both RBs got 19 touches last week, but Hill turned his into 96 yards, while Bernard totaled 67 yards.

Chargers at Ravens

After his hot start, 35-year-old Steve Smith seemed to get worn down, putting up low receiving totals and no scores in the games leading into the Ravens’ Week 11 bye. But Smith showed renewed vigor last week, grabbing six balls for 89 yards and a touchdown versus the Saints. Was that a one-week burst, or can Smith keep the energy going?

Raiders at Rams

Just when it seemed that the Raiders had finally found someone capable of fantasy relevance, Latavius Murray sustained a concussion after gaining 112 yards and two touchdowns on just four carries. Let’s all hope Murray can play, because he could do something special: make Oakland watchable.

Panthers at Vikings

Cordarrelle Patterson, Greg Jennings and Jarius Wright have all failed to seize the spotlight among the Vikings WR corps, but here comes Charles Johnson! The second-year player out of  Grand Valley State, who didn’t play as a rookie, has nine grabs for 139 yards and a score in his past two games.

Falcons at Cardinals

This is a perfect opportunity for Arizona to show that its recent offensive struggles can be attributed more to facing a pair of top defenses in the Lions and Seahawks, and less to the loss of QB Carson Palmer. Atlanta is last in total defense, so owners of RB Andre Ellington have reason to be optimistic.

Broncos at Chiefs

It’s a huge week in fantasy, with many teams down to their last chance to make the playoffs, which means that Julius Thomas  owners are frantically scouring news sources on any tidbit about the injured Bronco. Before hurting his ankle, Thomas’ production had become somewhat inconsistent, but if he plays, he’d still be a better option than almost any fill-in TE.

Patriots at Packers

Good luck to anyone starting LeGarrette Blount this week. Sure, he might be New England’s lead back, and get a hefty workload, but so might Shane Vereen, Jonas Gray, Brandon Bolden or James White. And that’s just the list of RBs currently on the team’s active roster. Who’s to say that Bill Belichick wouldn’t decide to give, say, fullback James Develin the work?

Dolphins at Jets

Rookie Jarvis Landry had already been a reasonable option in PPR leagues, but if he keeps up his recent penchant for scoring, he’ll be a low-end WR2 in all leagues. The Dolphins WR has scored four times in his past four games, averaging 8.0 targets in that span. Not bad for a guy getting about one millionth the publicity of fellow LSU product Odell Beckham Jr.
