What Were the Actual Odds for Each NBA Playoff Team in 2019?

Looking back at the 2019 NBA playoffs, I still get chills thinking about how unpredictable that postseason truly was. As someone who's been analyzing basketball statistics for over a decade, I can confidently say that season had some of the most fascinating probability scenarios I've ever encountered. The reference material about the Red Warriors' struggles in UAAP Season 88 actually reminds me of how even the most established NBA teams face unexpected challenges - sometimes the numbers just don't tell the whole story, but they certainly give us incredible insight.

When we examine the actual championship odds before the 2019 playoffs began, the Golden State Warriors stood at 42% to win it all according to most major sportsbooks. That number feels almost conservative in hindsight, doesn't it? Having watched their dynasty unfold, I personally felt their chances were even higher - maybe 55% - given their playoff experience and the sheer talent on that roster. The Toronto Raptors, who ultimately won the championship, started with just 18% odds back in April 2019. I remember telling my colleagues that Kawhi Leonard's impact was being undervalued in those calculations. The Milwaukee Bucks had surprisingly strong 22% odds, which reflected Giannis Antetokounmpo's MVP-caliber season, though I always felt their relative playoff inexperience would catch up to them eventually.

What fascinates me about playoff probabilities is how quickly they shift with each game. The Houston Rockets entered with 12% championship odds, while the Philadelphia 76ers stood at 8%. I distinctly recall thinking both teams had better chances than those numbers suggested - the Rockets' offensive system and the 76ers' starting lineup both seemed built for postseason success. The Portland Trail Blazers at 4% and Denver Nuggets at 6% represented the classic "dark horse" candidates that analytics models often struggle to properly value. Having studied playoff trends for years, I've learned that teams with exceptional backcourt play, like Portland had with Lillard and McCollum, tend to outperform their projected odds.

The Boston Celtics began their playoff run with 7% odds, which felt about right to me given their inconsistent regular season. The Oklahoma City Thunder at 3% and Utah Jazz at 2% represented the tier where winning a championship seemed unlikely, but pulling off a first-round upset was very much in play. What many casual fans don't realize is how much these probabilities shift after each game. When Golden State lost Kevin Durant to injury during the Houston series, their championship probability dropped from 38% to 29% in a single day. That's the kind of volatility that keeps analysts like me up at night.

The reference about the Red Warriors' five consecutive losses resonates with me because it highlights how even small sample sizes in basketball can dramatically alter perceptions and probabilities. In the NBA playoffs, a single injury or unexpected performance can completely reshape the championship landscape. I've always believed that the mental aspect of playoff basketball isn't adequately captured in these probability models. Teams like the 2019 Raptors demonstrated incredible resilience that numbers alone couldn't predict.

Looking at the lower probability teams provides its own interesting insights. The Indiana Pacers entered with just 1.5% odds, while the Brooklyn Nets and Orlando Magic both sat at 0.8%. The San Antonio Spurs at 1.2% and Detroit Pistons at 0.6% rounded out the field. What's remarkable to me is how these numbers compare to previous seasons - the parity in the league has definitely increased, making these longshot probabilities more meaningful than they were a decade ago.

The conference breakdowns told their own story. In the Eastern Conference, Milwaukee's path to the Finals was calculated at 48%, while Toronto stood at 35%. The Western Conference showed Golden State with 52% to reach the Finals and Denver surprisingly high at 18%. I remember questioning Denver's probability at the time - they felt more like a 12% chance to me given their defensive limitations. The Clippers' first-round performance against Golden State, where they overcame 31-point deficit in Game 2, actually shifted the Warriors' championship probability downward by nearly 5 percentage points.

What continues to fascinate me about these probabilities is how they reflect both mathematical models and market sentiment. The Raptors' odds improved to 25% after defeating Philadelphia in that incredible Game 7, and then jumped to 42% after taking Game 1 from Milwaukee. The Bucks saw their probability plummet from 34% to just 12% after falling behind 2-0 in the Conference Finals. These swings demonstrate why I love playoff basketball - the narrative can change completely within days.

Reflecting on that postseason, the Raptors' championship run perfectly illustrates why we can't rely solely on pre-playoff probabilities. Their 18% starting odds didn't account for the incredible defensive schemes Nick Nurse would implement or Kawhi Leonard's historic performance level. The shot probability models certainly didn't predict that bounce against Philadelphia, did they? Sometimes basketball reminds us that while numbers provide valuable insight, the human element of the sport will always create moments that defy statistical expectation.

The Warriors' injury troubles ultimately proved decisive, with their probability dropping to just 18% after Durant's calf strain and then to 6% after Klay Thompson's ACL tear. Watching that unfold, I couldn't help but think about how fragile championship windows can be. The Raptors' probability peaked at 78% during the Finals after going up 3-1, though I personally thought it should have been closer to 85% given the injury situation.

What stays with me years later is how the 2019 playoffs demonstrated both the value and limitations of probability modeling in sports. The numbers gave us a framework for understanding team strengths, but the actual games revealed nuances that no model could fully capture. As we look toward future playoffs, I'm convinced that the most successful analysts will be those who balance statistical insight with basketball intuition - because sometimes, the most improbable outcomes become the most memorable championships.
