Two bits of info to close up the loose ends in the sign-and-trade deal that delivered Kris Humphries from the Boston Celtics to the Washington Wizards:

• The Celtics generated a trade exception valued at $4.25 million. They have until July 19, 2015 to utilize it. (For those interested, Washington still has $4.3 million remaining on a trade exception generated from Trevor Ariza's departure).

• Washington sent a 2015 second-round pick to Boston that is top-49 protected, meaning the Wizards will have to be one of the top 11 teams in basketball, record-wise, next season to convey that pick to Boston. The good news: The way Washington has loaded up gives them a chance at that. The bad news: Picks in range 50-60 can usually be bought on draft night because of the long odds of that player faces to even make an NBA roster. Alas, an asset is an asset.

The gem here is the trade exception, which could help Boston facilitate roster additions down the road.
