The Celtics already are the best team (‘86), dynasty (Russell) and franchise (17 rings) ever.
This was a team that blew people out of the water any time they wanted, lost one game at home and basically just had the refs roll a ball out the rest of the season and watch the other team soil themselves. They admitted that if they really wanted to they would've won over 70 games. That was one team I'll never forget. They toyed with teams and turned it on if/when needed.
Parish, Bird, McHale, DJ, Ainge, Walton, Sichting, Wedman...you can't make this sh!t up. Let's not forget there were some tough teams in their conference (Philly, Milwaukee, Atlanta, Detroit were all good) that year as well.
