What happened: FantasyPros set Week 4 buy, sell and hold lines for fantasy football managers. The Week 4 window arrives with three weeks of regular-season usage and production in the books.

Why it matters: Early-season trade values shift fast once roles and workloads come into focus. Week 4 moves set depth before bye weeks and injuries test benches.

What to watch: Week 4 results will reset values ahead of Week 5 waivers and trade deadlines in early-deadline leagues.
