Based on the wiki, the Murray–Jefferson duo has top-3 QB-WR combo upside in the NFL for 2026, though there's a slight camp competition caveat baked in.
Here's why they're that high:
Justin Jefferson is ranked as a top-10 fantasy player (FantasyPros #9 overall) and is positioned for a "top-5 WR comeback" after his 2025 down year. The main catalyst: improved QB play. When Jefferson played with Carson Wentz for 5 starts in 2025, he averaged 95 yards per game — which would've ranked 3rd among all WRs. (from the Justin Jefferson page)
Kyler Murray is a six-time top-12 fantasy QB with arm talent and elite mobility. O'Connell's system has consistently produced functional-or-better QB play (Mullens averaged 370 YPG in spot duty). Murray as the heavy favorite (~90% odds to start) paired with Jefferson creates "WR1-overall potential," per the wiki. (from the Kyler Murray page)
Matthew Berry identified the Vikings as a "high-confidence breakout-offense candidate" with Murray and Jefferson as the centerpiece. (from the Vikings page)
The competition: The only thing holding this duo back from a consensus #1 ranking is the ongoing QB battle. Murray is the clear favorite, but J.J. McCarthy looked sharper at minicamp and is getting equal first-team reps. Oddsmakers give Murray a -1000 line (~90% implied probability), so it's more of a formality —
