Celtics vs Lakers: the rivalry that shaped the NBA
The Boston Celtics and Los Angeles Lakers are at the heart of one of the greatest NBA rivalries. These two teams virtually dominated the league throughout the 1960s and 1980s, engaging in unforgettable Finals matchups.
It all began in the ’60s, when Bill Russell led the Celtics and the Lakers countered with stars like Elgin Baylor and Jerry West. The two franchises clashed six times (1962, 1963, 1965, 1966, 1968, 1969), with the Celtics winning all six.
In the 1980s, the rivalry was reignited with Larry Bird representing the Celtics and Magic Johnson leading the Lakers. Their individual matchups resulted in three Finals: 1984 (Celtics win), 1985 (Lakers win), and 1987 (Lakers win).
The Celtics’ defensive discipline versus the Lakers’ speed and aggression captivated fans, helping spread the popularity of the NBA worldwide. This rivalry remains a cornerstone of the league’s legacy.
Pistons vs Bulls: the Bad Boys vs Michael Jordan
In the late ’80s and early ’90s, no rivalry was bigger than Pistons vs Bulls, featuring none other than Michael Jordan. The greatest player in NBA history led Chicago through bruising battles with the Detroit Pistons.
Despite Jordan’s brilliance, he wasn’t alone. The Bulls roster included Scottie Pippen, Dennis Rodman, Luc Longley, Steve Kerr, John Paxson, Toni Kukoc, Horace Grant, and head coach Phil Jackson.
Detroit’s infamous “Bad Boys” were relentless on defense. The squad featured Isiah Thomas, Joe Dumars, Grant Hill, Terry Mills, and at one point, Rodman—before he later joined the Bulls.
Between 1988 and 1990, the Pistons eliminated the Bulls three times, including twice in the Eastern Conference Finals. But in 1991, Chicago got its revenge with a stunning sweep led by Jordan.
Knicks vs Heat: intensity and physicality in the ’90s
From the East Coast came another fierce rivalry: New York Knicks vs Miami Heat. This tension-filled matchup peaked in the 1990s with repeated playoff clashes.
Games were marked by aggression and intensity. The Knicks featured Patrick Ewing, Charles Oakley, John Starks, and Anthony Mason. The Heat countered with Tim Hardaway, Glen Rice, Grant Long, Alonzo Mourning, and Rony Seikaly.
While neither team won a championship during the decade, the rivalry became legendary due to the fierce battles and the symbolic clash between two of the most iconic U.S. cities. Knicks vs Heat was not just about basketball—it was about identity and pride.
Warriors vs Cavaliers: a modern NBA rivalry
Among the newest NBA rivalries, Golden State Warriors vs Cleveland Cavaliers dominated the 2010s, clashing in four consecutive Finals (2015–2018). Golden State took home three titles (2015, 2017, 2018), while the Cavs won their first-ever championship in 2016.
The Warriors had an offensive powerhouse with Stephen Curry, Klay Thompson, and Draymond Green. Across the court, LeBron James led the Cavaliers with determination and power.
Other key Cavaliers during this stretch included Kyrie Irving, Kevin Love, Tristan Thompson, and Anderson Varejão. On the Warriors side, Kevin Durant later added even more firepower.
