Charles Sims

Week 1 at Arizona
Charles Sims didn't have an awesome performance last week, but he did enough to keep himself fantasy relevant as he finished with a receiving touchdown. He had seven touches for 41 total yards, while playing 31 percent of the team's offensive snaps.

Sims is able to do a lot with very little, which makes him a week-to-week flex play depending on the matchup. He doesn't get a great one this week, and therefore should be viewed as a low-end RB3.

Fantasy Upside
Despite playing behind the second-leading rusher in the league, Charles Sims found a way to be productive last season. He finished with over 1,000 scrimmage yards, and was the No. 22 back in standard and No. 17 in PPR.

He's a very capable runner, but his main contribution came through the air as he caught 51 passes for 561 yards and four touchdowns. He had at least three receptions in over half his games last season, just to emphasize his receiving ability.

Fantasy Downside
Sims is still the backup to Doug Martin, so getting touches doesn't come as easily for him. His ceiling will always be limited with Martin being the starting back. There will be some weeks where he doesn't score much, simply because he didn't get enough touches.

Bottom Line
Sims is a rare back who isn't really in a RBBC system, but still gets enough love every week to be relevant in fantasy. He won't get you the monster multiple-touchdown, 100-plus yard performances, but he will get you something, and there's value in a player like that.

Week 16 vs. Chicago

Charles Sims finished with 72 yards last week, which makes it three weeks in a row he's finished with at least 70 yards. That's a pretty impressive stat for a backup running back.

While Sims may not be an elite option, he's still proving he's a valuable asset. He'll look to prove that even more in a favorable matchup against Chicago this week. Sims should be viewed as a solid flex play.
