Should I Start J.K. Dobbins for Fantasy Football?
When the Denver Broncos drafted RJ Harvey in the second round of the 2025 NFL Draft, the expectation in the fantasy community was that he would take over the backfield quickly. The signing of Dobbins shortly after the draft was just seen as a move to build depth in the backfield.
Instead, Dobbins has served as the lead back in Denver for the first four weeks of the season. More importantly, he’s been very effective in that role.
J.K. Dobbins Rankings, 2025:
'Explosive' Runs (10+ yds.): 1st (11)
'Explosive' Run % (Min. 50 att.): 1st (19.3%)
Rushing Avg. (Min. 50 att.): 2nd (5.7)
Rushing 1st Down % (Min. 50 att.): 3rd (28.1)
Rushing Yds.: 4th (323) pic.twitter.com/EjSzmUKgB4— Tyler Gorse (@Tyler_Gorse_) October 2, 2025
Dobbins is currently RB16, averaging 14.3 PPR points per game. The veteran running back found the end zone in each of Denver’s first three games before failing to score in Week 4. He was still able to post a double-digit scoring performance thanks to 16 carries for 101 yards and one reception for four yards.
The veteran running back is averaging 14.3 carries, 1.8 targets, and a 51.3% snap share to start the season. Harvey will inevitably earn more opportunities as the season goes on, but Dobbins is proving that he will continue to be a significant part of the offense as long as he’s healthy.
Dobbins should be considered a mid-level RB2 in Week 5 against the Eagles.
Should I Start David Montgomery for Fantasy Football?
Montgomery could not find any space in Week 4 against the Browns. Montgomery had just nine carries for 12 yards in the 34-10 win. The veteran running back’s fantasy value has mostly been tied to scoring touchdowns this season, making him extremely matchup dependent thanks to changes along Detroit’s offensive line.
On the surface, Montgomery should have more space to operate in Week 5 against the Cincinnati Bengals. Cincinnati has struggled with Jake Browning under center, which should lead to a positive game script. Historically, this has led to a big rushing volume for Montgomery.
Montgomery should be considered a low-end RB2 heading into the week, but he can finish as a low-end RB1 if the game script goes in his favor.
Should I Start Chase Brown for Fantasy Football?
Brown is in the conversation for the biggest fantasy football disappointments in 2025. Brown was a revelation in 2024, finishing as the RB7 after Week 4 (when Zack Moss was injured) by averaging 18.3 PPR points per game. Brown had five weeks with 20+ fantasy points, largely thanks to his role as a high-volume, three-down back in one of the best offenses in the NFL.
The expectation entering 2025 was that he would maintain a similar role in an offense that lost no key pieces this offseason. Unfortunately, that has not been the case.
Brown currently sits as the RB33 in PPR scoring, averaging 9.4 points per game. He has just two games with 10+ fantasy points this season despite logging a 70+% snap share in three of four games. Brown is averaging just 2.3 yards per carry this season with one rushing touchdown.
An injury to Joe Burrow certainly hasn’t helped Brown find running lanes, but the Bengals' offensive line has struggled this year as well. The Bengals are last among NFL teams in yards before contact (1.1) and explosive rush rate (2.6%) this season.
Brown should be considered a low-end/fringe RB2 based purely on volume. He has handled at least 10 carries and at least three targets in every game this season. However, Week 5’s opponent, the Detroit Lions, is one of the best run defenses in the NFL this season. They are the third-best defense against the run in expected points added (-20.5) and are sixth in stuff rate (25.5%).
If you have better options on your bench despite bye weeks and injuries, this may be a good week to start them over Brown. At the very least, he will get enough volume to have a chance of finding his way into your fantasy lineup in Week 5.
