Week 8 fantasy football quarterback rankings are in, and the biggest change is simple: four teams are on bye, taking Brock Purdy, Tyler Shough, C.J. Stroud and J.J. McCarthy out of the pool. Michael Fabiano opened the week with a reminder that fantasy managers need to adjust quickly before lineup deadlines tighten.
That matters now because Week 8 is already forcing lineup decisions, and the shortage at quarterback is real. With the 49ers, Giants, Saints and Texans idle, managers who had been counting on those passers need another option immediately. Fabiano framed it plainly: there are risers, there are fallers, and the rankings are being shaped as much by availability as by form.
Among the movers, Dak Prescott and Kyler Murray moved up. That gives fantasy managers a cleaner path at a position that can thin out fast when byes arrive. It also explains why the weekly list is being searched so heavily: people want to know where the safe starts are before the weekend games begin, and Prescott and Murray are part of that answer.
The harder read is at the top end. Patrick Mahomes and Bo Nix have both seen their value fall, even though they meet this weekend in Denver. Fabiano described that matchup as an important AFC West battle, but the ranking drop shows that name value alone is not enough in a week built around matchup math and streaming choices. That is the friction in Week 8: a marquee game can still leave both quarterbacks less attractive for fantasy purposes than the labels on the jersey suggest.
Fabiano said to keep checking back for updates, especially after the final team injury reports come out late in the week. That is the real next step for managers using these NFL power rankings Week 8: lock in the bye-week replacements now, then revisit the board once the injury picture is complete.
