Welcome to the Waiver Warehouse, your one-stop emporium for upgrades and Band-Aids. Each week we’ll list the best widely available free agents for fantasy football. (We define “widely available” as being owned in less than half of all Yahoo leagues.) We’ll also list a few more names in the “window shopping” category—players worth monitoring or perhaps worth rostering in deeper leagues. In addition to a brief overview of each player, we’ll grade each player on talent, opportunity and schedule (with an emphasis on near-term schedule), then provide a composite grade. Please note that for quarterbacks, we replace the opportunity grade with a grade for the QB’s supporting cast.
