What are the Celtics' options with their draft picks when it comes to trades?

The Celtics have two options when it comes to trading draft picks. The first is to agree to a trade on the night of the draft. In that scenario, the rights to a player can be traded and said player holds no salary matching value in a trade (since the player is unsigned). This is the most common sort of trade you will see on draft night with one team simply drafting who another team wants at their spot.

The other (rarer) way rookies can be traded upon being drafted is after they sign their rookie contract. In this instance, any team can trade a player 30 days after they sign a contract. In this version of a trade, a rookie's salary slot counts as salary in a deal and can be used to help make the money match up in a trade for a veteran player with a sizable salary.

What is a good example of this type of deal?

The most prominent example was in 2015 when the Cavs drafted Andrew Wiggins at No. 1. Days later, LeBron James agreed to a deal with the Cavs, which created a more win-now mindset for the franchise. More than thirty days after Wiggins signed his contract, he was dealt with Anthony Bennett and Thaddeus Young as part of a three-team trade in late August which ended up with Love landing in Cleveland. Wiggins' salary was used as part of the salary matching needed to help even things out with Love's big salary.

Could this type of trade come into play for the Celtics this summer? How would it work?
