The Toronto Raptors pulled off arguably the biggest trade in franchise history by landing Kawhi Leonard from the San Antonio Spurs, at the expense of giving up DeMar DeRozan -the heart and soul of this team for nine years.

Toronto also got shooting guard Danny Green in the trade, while packaging big man Jakob Poeltl and a protected first-round pick. Indeed, it's the biggest NBA trade of the 2018 offseason, and we may not see a move like it for a long time.

This trade will certainly shake up the NBA landscape for next season, as the Raptors look like the team to beat in the Eastern Conference. As for the Spurs, they'll have to try to find a way to regroup after being forced to deal away the franchise star.

So, which parties benefited most from this trade, and which ones are probably shaking in their boots? Let's take a look at the biggest winners and losers from the Kawhi Leonard trade.

The definition of insanity is trying the same things over and over again and expecting different results. The Raptors knew it was time to make a big change or two, and it all started with firing head coach Dwane Casey.

Team president Masai Ujiri simply wasn't content with a roster that won a franchise record 59 games last year, and he saw the opportunity to trade for a top-five player in the world. And he made it happen.

Losing DeRozan hurts, but he's not on the same level of Leonard. The Raptors just weren't going to be a title contender with the DeRozan-Kyle Lowry duo. Leonard single-handedly turns this team into a top-tier unit, if they weren't already

Even if Leonard leaves next summer (who said he may not like Toronto and won't re-sign?), the Raptors had to make the trade. Leonard is the game's defensive player and puts them on a much better path to reaching the Finals. It also helps that Eastern Conference bully LeBron James went to the Los Angeles Lakers.

The Celtics and 76ers, like the Raptors, were big winners when LeBron decided to join the Lakers. But Boston and Philadelphia undoubtedly had better all-around rosters than Toronto, and they looked like the two teams to beat in the East.

Not anymore. Both teams were linked to Leonard in trade rumors, but none of them were willing to part with young roster players. That allowed the common enemy, Toronto, to swoop in and land the two-time Defensive Player of the Year.

Leonard automatically becomes the best player in the Eastern Conference. And even if Boston and Philly have more young star power, the Raptors have a better bench. They've become the team to beat.

If the Raptors wind up winning the East next year, the Celtics and 76ers will surely regret passing up on the chance to trade for Leonard. None of them have a player of his caliber on the roster.

Winner: Kawhi Leonard

Leonard requested a trade in the offseason after a falling out with Spurs coaches, teammates and management. When it became clear the Lakers, Celtics and 76ers wouldn't offer up the right packages for him, it looked like Leonard would be forced to start (or even sit out), 2018-19 in a Spurs uniform.

Instead, Leonard gets traded to a championship contender - rather than a bottom-feeder. He joins a great basketball city, which will come to admire and love Leonard right away. Imagine if he was traded to a non-playoff team. That would waste a year of Leonard's prime.

Instead, he has a chance to reach the NBA Finals with the Raptors. They have a great atmosphere, and he'll fit the offense perfectly. Even if he opts to only stay in Toronto for one year, at least Leonard got to play for a strong team before entering free agency.

Loser: DeMar DeRozan

DeRozan isn't a loser for being traded to the Spurs - who have defined excellence and consistency over the past 20 years. But he's clearly hurt that the team opted to trade him, as you could tell by his Instagram story.

DeRozan didn't pull a Vince Carter or Chris Bosh. He stayed with the Raptors for nine years, opting not to chase a championship ring for an American team. DeRozan stayed with Canada's only team, and turned them into a perennial playoff team.

You can understand why DeRozan is hurt. He was extremely active in the Toronto community, and DeRozan was promised he'd never get traded. Ujiri obviously decided to flip the switch, and it's not sitting well with one of the best athletes in the history of Toronto.

He now heads to a Spurs team that figures to be a top unit in the West next year. But in this case, there's no place like home for DeRozan. And the Raptors decided his loyalty wasn't enough.

On one hand, the Spurs are losers for being forced away to deal their franchise player, without receiving a giant package of youth roster talent. Getting Brandon Ingram, Kyle Kuzma and draft picks from the Lakers would have been a beautiful haul, but it didn't pan out that way.

On the other hand, the Spurs do get a bonafide star in DeRozan. Keep in mind this team won 47 games last year, with Leonard only appearing in nine contests. With DeRozan, they're easily a 50-55 win team.

Head coach Gregg Popovich emphasized that it's time to move on (via ESPN.com), and that he's excited to work with DeRozan, who joins a core that consists of Rudy Gay and LaMarcus Aldridge. The Spurs now have the drama out of the way. They have a superstar in DeRozan to work with the other standout veterans on this team.

So yeah, call them a winner and a loser. There's goods and bads for the Spurs here.
