Ron Harper -- '96 Bulls Would BEAT '15 Warriors ... Period.

The Golden State Warriors are good ... but they're NOT the 1996 Chicago Bulls ... so says Ron Harper who says his squad is the greatest NBA team of all time.

The Warriors are 12-0 and dominating -- crushing opponents by an average of 15 points a game ... drawing comparisons to the legendary '96 Bulls ... the first team to ever win 70 regular season games.

We asked Ron if he thought the Warriors had a shot to break their record (72-10), he didn't hold back.

"Records are made to be broken but that Bulls team was built on defense and was a BETTER team than the Golden State Warriors."

Harper added, "and no one wins a championship in November and December."

FYI -- the Bulls started 10-2 through their first 12 games ... with superstars like Michael Jordan, Scottie Pippen, Toni Kukoc and Dennis Rodman playing out of their minds on their way to an NBA title.

By the way, Steve Kerr was also on the '96 Bulls team ... and happens to be the current coach of Golden State.
