Waivers are where teams or owners can select players who are not currently on a league roster. In order to select a player from this pool, an owner must make a claim. However, there will be a freeze (typically until late Tuesday night/early Wednesday morning) on these players so that every owner has a chance to enter a claim. Priority is given to the owner who is higher up in the waiver order. Once the waiver claims are made, players who were not claimed become "free agents" and can be added by any owner on a first come, first served basis up until players lock again when their next game kicks off. The waiver order and pool of players can reset each week.
