Marvin Harrison Jr. - Start 'Em, Sit 'Em Fantasy Football Picks for Week 1 (2026)

September 5, 2026

Marvin Harrison Jr. start 'em, sit 'em fantasy football picks for Week 1 of 2026. Should you start or sit Marvin Harrison Jr. for fantasy football lineups in Week 1?

BALLER MOVE: Start as WR3 in 12-Team PPR leagues

POSITIONAL VALUE: WR3/FLEX

ANALYSIS: Are NFL fans being too harsh on Marvin Harrison Jr.? The Ohio State product was picked fourth overall in 2024 and had an objectively solid rookie season, which was unfortunately overshadowed by Brian Thomas Jr., Malik Nabers, and Ladd McConkey's outstanding rookie campaigns.

Overcoming a horrid quarterback situation, MHJ was well on his way to a 1,000-yard season through the first eight games of his sophomore season.

However, he missed time due to an emergency appendectomy in November, and subsequently suffered heel and foot injuries that essentially ended his season.

Regardless, the 24-year-old is still on a positive trajectory compared to his Hall of Fame father. Marvin Harrison Sr. didn't have a 1,000-yard season until the age of 27, which was Peyton Manning's sophomore season.

The Cardinals obviously do not have sophomore Peyton Manning, or anyone even half as good. The team is also set up to run more than they pass, due to their overloaded running-back room, which is the complete opposite of last year.

In 2025, the team suffered many injuries in their RB room, which, combined with the coaching staff seeing the writing on the wall, contributed to their ridiculously high pass rate near the end of last season.

Those circumstances favored Michael Wilson tremendously, and who knows? Had Harrison Jr. been healthy, he would most likely have been the main beneficiary. Despite Wilson's recent contract extension, Harrison Jr. was treated as the team's WR1 in training camp, per Theo Mackie of The Arizona Republic.

Harrison Jr.'s quest for his first 1,000-yard season will begin on Sunday against the Chargers. Their defense allowed the eighth-fewest PPR points to WRs last season, and he was unimpressive in his only prior game against them in 2024.

Plenty of things are working against him, but he'll have a good chance of racking up points if the team falls into a large deficit early on.
