How does it work?
Waivers are the process by which owners can select from the pool of
available players who are not on a team's roster in the league. They may
have been undrafted or dropped by owners. Owners can put a claim for
that player, but must wait a specified amount of time until the waiver
clears. The team that puts a claim on a player - and who has the higher
waiver priority number - will receive the player when waivers clear.
