No team in NBA history could beat Golden State in a 7 game series.
Even this year's 1st Team All-NBA team of Kawhi, LeBron, Anthony Davis, Harden and Westbrook would struggle to co-exist as well as the shooters on the Warriors. Too many ball-hogs and not enough efficient shooting. Harden and Westbrook are both 34% three point shooters. They would each fight over the ball jacking up shots. Even if they allowed LeBron to run the offense, they aren't good enough shooters off the ball to win a shootout against a team of superstar 42% three point shooters.
The team is the culmination of decades of athletic evolution and perfection of the sport. Their four superstars are scientifically engineered for the modern style of NBA basketball. Steph Curry is the best shooter to ever live. Kevin Durant is the greatest pure offensive player to ever play the game. Klay Thompson is of the 5 best shooters of all time. Draymond Green is an ideal glue-guy Superstar.
Do you know how many players in NBA history have averaged at least 19 points, at least 1 three pointer per game, while shooting at least 37% from three? Six. They have half of them. The six players: Durant, Curry, Klay, Dirk, Mitch Richmond and Michael Redd.
You wouldn't beat them with Richmond, Redd and Dirk.
Golden State is unbeatable.
