What can we say about these seasons? Well first, the Warriors won championships in both. And they were the Philadelphia Warriors back then.
The problem is that in 1946-47, there wasn't even an NBA yet. The Warriors were the champions of the Basketball Association of America. The BAA would eventually become the NBA, but obviously that transformation had yet to happen.
That 1946-47 team was led by rookie Joe Fulks, a Warrior great. He was named to the NBA's 25th Anniversary Team, and during the title season he averaged 23.2 points per game.
By the time the 1955-56 season rolled around Fulks was no longer on the team, but the Warriors were more than adequately led by Paul Arizin and Neil Johnston. Both were named to the All-NBA First Team.
Arizin bears some mentioning here. He was a 10-time All-Star and was named to the NBA's 50th Anniversary Team, so he really was one of the best players of all time.
Then why on earth would we combine these two title winning teams? And why aren't they higher?
Well in 1947 there were only 11 teams in what wasn't even the NBA yet. It was actually the BAA's first year.
Of course, there was no three-point line, and the shot clock had yet to be invented.
In 1956, the league had actually shrunk to only eight teams. There was still no such thing as a three, and the shot clock had only been around for a couple years.
So yes, these teams deserve to be celebrated. But they don't stand the test of time. They are part of the Warriors history, but in this discussion, they can only be mentioned.
