@MikeTriplett @ESPNNFL is it too early to give up on CJ Anderson? DEN has played two good Run Defenses. Detroit isn't as strong vs. run. — Chase Cartwright (@CMCartwright15) September 24, 2015

@MikeTriplett: The Denver Broncos backfield was a popular subject in this week's mailbag -- a trend that Broncos reporter Jeff Legwold expects will continue.

"I expect them to frustrate fantasy football players all year," said Legwold, who said he tried to warn people not to buy into the hype of C.J. Anderson as a top-five fantasy pick this year because of coach Gary Kubiak's history of rotating backs.

The good news is that Anderson and Ronnie Hillman should be fantasy-relevant -- and no, you should not give up on Anderson if he is already on your roster. The bad news is that Legwold doesn't expect either to emerge as a leading man.

"They're gonna split it. Gary likes 'em both and that's how it's gonna be," Legwold said. "Ronnie has looked the best, but he's not very big, so I think he has a threshold regardless of how great he's doing. C.J. is going to be an early-down guy a lot of the time. But when all is said and done, both are going to get plenty of carries."

Legwold said he expects the touchdowns to go to whomever has the "hot hand."

On a positive note, Legwold said the next four games should provide ample opportunity for both to succeed. Not only are they playing four subpar run defenses (Detroit, Minnesota, Oakland and Cleveland), but he expects Denver to run the ball more and use the screen-passing game more to get people to "back off" Peyton Manning, who has been blitzed on 45 percent of his pass attempts by Legwold's count -- easily the highest total of his career.

@MikeTriplett @ESPNNFL With Hill's poor performance last game, and solid numbers from Giovanni Bernard, will Bernard get more touches? — Jim John (@ohHItj) September 24, 2015

@MikeTriplett: Speaking of top fantasy picks who are stuck in two-headed backfields, we go to the Cincinnati Bengals' Jeremy Hill and Giovani Bernard.

Hill had an awful day last week, fumbling twice, getting benched in real life and actually scoring negative-one point in ESPN's standard fantasy scoring. But as Bengals reporter Coley Harvey wrote, the Bengals aren't giving up on Hill yet and hope the humbling experience will benefit the second-year pro going forward.

"As great as Giovani Bernard's 20-carry, 123-yard performance in last week's win over San Diego was, it won't cause the Bengals to change the running back plans they established when the season began," Harvey said. "Offensive coordinator Hue Jackson said early in the week that he had no plans of moving away from Jeremy Hill as his primary back. ... Chalking it up to him having a bad day, they believe that lesson was learned.

"It's possible Bernard may get a few more touches moving forward than were anticipated for him, but don't expect a sudden dramatic increase. The Bengals value their two-back system and believe that it works well."

@MikeTriplett @ESPNNFL who is going to stay the most reliable flex: James Jones, Travis Benjamin, or Abdullah? — Joshua Barham (@JoshuaBarhemoth) September 24, 2015

@MikeTriplett: Great question since it involves three players who are hard to gauge. Receivers James Jones and Travis Benjamin have played out of their minds so far, while Detroit Lions rookie running back Ameer Abdullah has yet to tap into his exciting potential.

ESPN fantasy analyst Eric Karabell ranked Abdullah 11 spots ahead of Jones in his flex rankings this week. But both Lions reporter Michael Rothstein and Cleveland Browns reporter Pat McManamon recommended Jones when I posed this question to them.

Rothstein said he thinks Abdullah will eventually emerge as Detroit's leading man, if he's not there already. And he thinks Abdullah will eventually take over some of the nickel pass-catching snaps that are currently going to Theo Riddick. But he said for now, "I wouldn't feel comfortable using Abdullah on a week-to-week basis until I see improvement from the run blocking." The Lions rank 31st in the league with 53.5 rushing yards per game.

Rothstein did stress, however, that Abdullah should get regular touches every week and will catch some passes, so he is at least a safe play.

As for Jones, Green Bay Packers reporter Rob Demovsky said he will stay involved since QB Aaron Rodgers "really trusts him, and he's big on guys who know what the heck they're doing.

"Jones will fight for the ball and make the tough catches," Demovsky said. "However, he's limited athletically, which means his targets might never be as high as Randall Cobb's or Davante Adams.'"

Last but not least is Benjamin -- who is the first player since Jim Brown to score four 50-yard touchdowns in the first two weeks of a NFL season. McManamon had a great breakdown this week on how the Browns plan to keep it going.

Obviously, defenses will start paying more attention to the dynamic speedster now. But McManamon said Benjamin has proven to be more of a polished receiver than it seemed when he was drafted. He pegs Benjamin as a third or fourth receiver on fantasy teams, with the upside to be more.
