In many professional sports leagues, one team is not allowed simply to purchase a player from another team, so they have to trade which requires:  a double coincidence of wants.

What is Trade Sport?

In professional sports within the United States and Canada, a trade is a sports league transaction between sports clubs involving the exchange of player rights from one team to another. Though player rights are the primary trading assets, draft picks and cash are other assets that may be supplemented to consummate a trade, either packaged alongside player rights to be transferred to another team, or as standalone assets in exchange for player rights and/or draft picks in return. Typically, trades are completed between two clubs, but there are instances where trades are consummated between three or more clubs.

Trades only involve players who are under contract with their current teams. Free agent players, whose contracts have expired, cannot be traded by their former teams, and are free to join a different team.
