Okay. I'll give it a try.
PG Walt Frazier
SG Donovan Mitchell
SF Scottie Pippen
PF Robert Horry
C Bill Russell
John Havlicek
Tiny Archibald
Bob Pettit
Willis Reed
Jerry Sloan
Rotation Notes: Havlicek will play more minutes than Mitchell and Pettit near the same as Horry. The rotation was designed to make logical sense in terms of defensive and offensive rotations. Sloan will not play much because the other 9 guys are known for playing multiple positions and heavy minutes.
My team is built on championship pedigree + defense + shooting. This team is made up of winners. Everybody on my roster, outside of Mitchell and Sloan, was a key part of championship teams. These guys would do whatever it takes to win. They all play defense. They all were passers with above average assist rates. They were all known as guys who would fight for everything. They all sacrificed on behalf of the team. With this group of guys, chemistry would never be an issue.
This is the best defense in this competition because every player on my team (outside young Donovan) was either an All Defense regular or was a major defensive difference maker for title winners. The team is super athletic, long and able to switch on multiple positions. Pippen is considered the best perimeter defender of all time. Russell is considered the best defensive center in the history of the league not named Wilt. Havlicek was Pippen before Pippen and also known as the greatest 6th man in the history of the NBA. Frazier was a 6'4" 7 time All Defense. Horry won 7 titles as a beast switchable defender.
Every PG, SG, SF and PF on my roster is a 3 point threat. It's a team full of shooters who defend at the highest level and all pass better at a higher than average rate.
