Allocation ranking

The allocation ranking is the mechanism used to determine which MLS club has first priority to acquire a player who is in the MLS allocation list. The MLS allocation list contains select U.S. National Team players and players transferred outside of MLS garnering a transfer fee of at least $500,000. The allocations will be ranked in reverse order of finish for the 2016 season, taking playoff performance into account. Two expansion teams will take the top spots.

Once the club uses its allocation ranking to acquire a player, it drops to the bottom of the list. A ranking can be traded provided that part of the compensation received in return is another club's ranking. At all times each club is assigned one ranking. The rankings reset at the end of each MLS season.
