Which NBA teams had the best offseasons?

With the bulk of this summer's moves in the books, we'll be grading each team based on the results of the draft, free agency, trades and, in some cases, coaching changes.

Because teams did not all have the same ability to improve coming into the offseason, these grades are based on how well teams utilized their cap space and draft picks, rather than on which teams did the most to improve. The grades also balance short-term and long-term goals, so as to reward teams that aren't focused on putting together the best possible roster for the upcoming season.

With that context in mind, and having graded the Eastern Conference last week, let's wrap things up with the West.
