Despite a long period of inactivity on the NBA trade market, multiple teams chose to do something in the last few hours before the deadline on Thursday. Nine deals were finished and 25 players changed employers.

Let's start with the biggest one.

The Golden State Warriors sent D'Angelo Russell, Jacob Evans III and Omari Spellman to the Minnesota Timberwolves and acquired Andrew Wiggins and a 2021 top-3-protected first-round draft pick.

First, congratulations to the Warriors for managing to avoid a luxury tax this season. Though they still have four open roster spots, signing a few reasonable minimum contracts will never raise their total salaries above the luxury line again. The team could rest assured and continue to tank for a high pick in the 2020 NBA Draft.

Wiggins' arrival is a more complicated case. First, as a swingman, he should be more compatible with Stephen Curry and Klay Thompson than D'Angelo Russell. Second, Wiggins' physical talents are still there and he only missed nine games in the previous five seasons. Third, though he's been criticized for lacking aggressiveness in his game, Wiggins kept a 60.5-percent field-goal-rate in the paint and was able to earn an average of 4.9 free throws per game. Besides, he improved his 3-pointers which he could make 2.2 at a rate of 33.1 percent per game and assists which he could deliver 3.7 on average.

However, Wiggins still has four years left of his contract and they are worth about 106 million U.S. dollars. As for his skills, to put it in a nice way, the Warriors are Wiggins' best option to learn passing, give-and-go play, screen play, catch-and-shoot; to put it in a bad way, the 25-year-old is still way short of meeting the Warriors' needs in these areas.

Things are much simpler and clearer for the Timberwolves. First, they kept their first-round pick for this year and, considering their current record of 15-35, this pick may be quite valuable next summer.

Second, they finally clarified who will lead the team. Karl-Anthony Towns and his best friend Russell can make the best screen pair of the league and bring remarkable offense for the Timberwolves.

The above is the bright side; now let's look at the dark one. Russell and Towns are the worst maximum-contract defenders in their positions. Meanwhile, the team's front office still has a lot of work to do before they can build a workable squad around the pair.

The Los Angeles Clippers sent Jerome Robinson to the Washington Wizards in exchange for Isaiah Thomas, sent Maurice Harkless, a 2020 first-round pick, a 2021 second-round pick and 2021 first-round pick swap (top 4 protected) to the New York Knicks in exchange for Marcus Morris.

Thomas is very likely to be waived by the Clippers and Robinson only received an average of 9.7 minutes in the Clippers this season – neither of them matters. This deal is simple: the Clippers landed an important champion piece.

Morris averaged 19.6 points and 5.4 rebounds per game while shooting 6.9 triples per 36 minutes at a 3-point rate of 43.9 percent. He will be the best stretch-out player of the Clippers and make the opponents' defense pay when they try to double team Kawi Leonard or Paul George.

Morris is not a great defender, but it's a different story when he takes on strong forward or even center one-on-one. During his time in the Boston Celtics, he did a good job of defending LeBron James.

Though the Lakers were not involved in this deal, they were the last one to want it to happen. It's bad enough for the purple and gold to miss Morris but watching him join the Clippers, their biggest rival in the West, is disastrous.

Since there's no doubt that the Clippers will remain as one of the biggest champion candidates in the coming two years, the draft picks they gave the Knicks were the least cost option.

The Detroit Pistons sent Andre Drummond to the Cleveland Cavaliers, acquired Brandon Knight, John Henson and 2023 second-round pick (the lower one between the Cavaliers and the Warriors).

This is the most confusing deal on Thursday. The value of Knight and Henson are no more than two expiring contracts. Drummond has player option for his last year of the current contract in 2020 summer. Simply speaking, the Pistons gave away a center who averaged 15.8 rebounds this season and 13.7 rebounds in his career for a second-round pick.

Some may argue that the Pistons sent Drummond away to collect salary space. It's true that the team may have about 35 million U.S. dollars on their payroll space in summer after the deal – enough to offer a maximum contract – but seriously, when was the last time a superstar joined the Pistons by choice?

The Miami Heat sent Justise Winslow, Dion Waiters and James Johnson to the Memphis Grizzlies, acquired Andre Iguodala, Solomon Hill and Jae Crowder. Then the Grizzlies traded Johnson to the Timberwolves in exchange for Gorgui Dieng.

The most valuable part of this deal is Iguodala and we have already reported about it. The Heat failed to introduce Danilo Gallinari from the Oklahoma City Thunder but they managed to squeeze more from the Grizzlies. First, neither Waiters nor Johnson plays an important role in the Heat's roster anymore, not to mention that John has no reason not to exercise his 16.05-million-U.S.-dollar contract this summer. By accepting the expiring contracts of Hill and Crowder, the Heat collected quite some space on their payroll.

In fact, Pat Riley is again playing the long game. Although he gave Iguodala a two-year, 30-million-dollar deal, the second year has a team option. By 2021 summer, the Heat will only have Jimmy Butler's maximum deal and Tyler Herro's rookie contract to pay if they choose to opt out of Iguodala's contract. Meanwhile, Giannis Antetokounmpo will hit the free agent market by then. Besides, Kawhi Leonard and Paul George both have player options at that time.

The deal does not sound so good for the Grizzlies. Though Hill and Crowder are not star players, they have the fourth- and the eighth-longest longest time on the court. One of the reasons that they can rank the eighth in the West at the moment was their long rotation. Furthermore, the contracts of Waiters and Dieng will continue to occupy space on the team's payroll next season. The only thing the Grizzlies can count on is that Justise Winslow can come back healthy and improve himself faster than before.

Other deals on Thursday:

The Clippers sent Derrick Walton Jr. to the Atlanta Hawks for cash.

The Houston Rockets sent Jordan Bell and a 2023 second-round pick swap to the Grizzlies for Bruno Caboclo.

The Denver Nuggets sent Shabazz Napier to the Washington Wizards for Jordan McRae

The Portland Trail Blazers sent Skal Labissière and two million U.S. dollars to the Atlanta Hawks.

The Philadelphia 76ers waived Alec Burks and traded James Ennis to the Orlando Magic for a 2020 second-round pick.
