the event two or more clubs file a request for the same player on the same day. The allocations will be ranked in reverse order of finish for the 2012 season, taking playoff performance into account. 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 League season. On December 12, 2012, Portland Timbers acquired the number 2 ranking from Chivas USA in exchange for the number 3 ranking and an international roster spot. On February 19, 2013, Chivas USA traded the No. 3 ranking to Seattle Sounders FC in the Shalrie Joseph trade. It was also reported that Seattle sent the No. 15 allocation ranking to Chivas USA as part of the deal, although Seattle appeared to have owned the No. 16 selection and not the No. 15 selection. On July 1, 2013, Chivas USA acquired the number 1 allocation ranking from Toronto FC in exchange for the #16 ranking, a first-round pick in the 2015 MLS SuperDraft, and an international roster spot. Weighted lottery Some players are assigned to MLS teams via a weighted lottery process. A team can only acquire one player per year through a weighted lottery. The players made available through lotteries include: (i) Generation adidas players signed after the MLS SuperDraft; and (ii) Draft eligible players to whom an MLS contract was offered but who failed to sign with the League prior to the SuperDraft. The team with the worst record over its last 30 regular season games (dating back to previous season if necessary and taking playoff performance into account) will have the greatest probability of winning the lottery. Teams are not required to participate in a lottery. Players are assigned via the lottery system in order to prevent a player from potentially influencing his destination club with a strategic holdout.
