What do you mean, sign first and then change?
Sign first and then change, which is an NBA term, meaning that players renew their contracts with the home team and then trade immediately. If the transaction cannot be completed within 48 hours, the signing is invalid. The condition of signing first and then changing is that both parties to the transaction have negotiated the terms of the transaction. The main purpose is to make the bargaining chips fairer and protect the interests of both teams and players. In the NBA, it is very common to sign first and then change, especially for big-name stars with large contracts.
The NBA benefits of signing first and then changing.
The advantages of signing before changing in NBA are as follows: first, the home team of the player avoids losing the player in vain. If a player signs with the home team first, his next team must exchange equal chips. Then, the interests of the players are guaranteed. In NBA rules, under certain conditions, signing a contract with the home team can get a higher salary. For the other side of the transaction, sometimes signing first and then changing is the basis for the player or the player's home team to agree to the transaction. Sometimes you can't sign a contract directly because of the salary cap. Signing before changing is a necessary condition for trading.
Did James sign before he joined the Heat?
James joined the Heat on the basis of signing first and then changing. On July 20 10/0, the Heat signed first and then won James, and the Cavaliers got four draft picks and a transaction of1450,000 was abnormal. James could have signed the Heat naked, but he chose to sign first and then change to protect the Cavaliers' interests to the greatest extent. The rights of the draft and the special circumstances of the transaction are very practical. At the same time, because it is a transaction rather than a contract, the Heat can continue to sign other players besides the salary cap, which is considered to maximize the interests of both parties.
