David Johnson is on the ever-growing COVID-19 list. Rex Burkhead was supposed to have a large role moving forward, but he injured his hip and was forced out early. Royce Freeman stepped up and finished with 11 carries for 15 yards and six catches for 51 yards. Quarterback Davis Mills won't be throwing the ball 40+ times in every game and will look to get the backfield more involved for the rest of the season. Freeman is one of the top streaming options in fantasy football this week and is a good FLEX player.Rashaad Penny - Seattle SeahawksCorbin K. Smith@CorbinSmithNFLRussell Wilson on Rashaad Penny's breakout outing and the offensive line's dominance vs. Texans.5:46 AM · Dec 12, 2021342Russell Wilson on Rashaad Penny's breakout outing and the offensive line's dominance vs. Texans. https://t.co/LLM9vEXKkOHead coach Pete Carroll stated the Seattle Seahawks were going to run with a rotating committee in the backfield until further notice, but he also pointed out Rashaad Penny as someone who deserves a chance to be the starter. Penny had over 25 fantasy football points last week with 137 rushing yards and two scores. If the Seahawks allow him to carry the load, he is easily a RB2 for the rest of the season.Craig Reynolds - Detroit LionsPFF Bet@PFF_BetHighest graded RB in Week 14 (min. 25 snaps)Craig Reynolds (84.0)4:01 AM · Dec 13, 20212751348Highest graded RB in Week 14 (min. 25 snaps)Craig Reynolds (84.0) https://t.co/grOZkLpansThe Detroit Lions were without both D'Andre Swift and Jamaal Williams, which allowed the unknown Craig Reynolds to outproduce Godwin Igwebuike and Jermar Jefferson with 83 rushing yards. The Lions face the Arizona Cardinals this week, and Reynolds could still have a featured role. Even if Williams is available, Reynolds has earned himself, at least, one more week as a fantasy football starter.D'Ernest Johnson - Cleveland BrownsCLEology@_CLEology#Browns Top Offensive Grades Per PFF (70+ / min. 20 Snaps) - Week 14 v BAL 1.)

Johnson had four carries for 22 yards when filling in for Hunt this week and should see a bigger workload behind Nick Chubb against the Las Vegas Raiders. With Jarvis Landry on the COVID-19 list, Johnson could also see a season-high number of targets as a receiver.Rhamondre Stevenson - New England PatriotsPFF NE Patriots@PFF_PatriotsThe Patriots are the only team to have two RB’s with 80+ rushing grades this season🔹 Damien Harris: 83.9 rushing grade (8th)🔹 Rhamondre Stevenson: 81.9 rushing grade (10th)10:53 AM · Dec 6, 20211451153The Patriots are the only team to have two RB’s with 80+ rushing grades this season🔹 Damien Harris: 83.9 rushing grade (8th)🔹 Rhamondre Stevenson: 81.9 rushing grade (10th) https://t.co/SCSvVngU6kDamien Harris is still considered the starting running back after putting up over 100 yards in his last outing. However, he is dealing with a hamstring injury and could be out for Week 15 or, at least, limited. Rhamondre Stevenson has proven himself to be a starter in the NFL and is worth starting in fantasy football, whether Harris plays or not. If Harris is out, he's a nice RB2 for Week 15.Also check out: Complete Monday Night Football Schedule 2021
