One notable example would be Quinn Buckner, whose career was built around his defense
Very good to excellent defender. But played just 1/26 of the Bucks total minutes those 6 seasons.
Paul Pressey, also a fantastic defensive guard
Played primarily SF. Their guards were the likes of Moncrief, Buckner, Brian Winters, Phil Ford, Nate Archibald, Lorenzo Romar, Craig Hodges, Kevin Grevey, Ricky Pierce. But yes Pressey was an excellent defender.
This isn't necessarily trying to take something away from Moncrief. But those elite DRtg's very much feel like an ensemble effort most years
With Moncrief playing almost 1/7 of their total minutes played over those 6 seasons, those Bucks were the league's dominant defensive team.
And those 6 years Moncrief played the most minutes among the league's SGs. But other SGs who played a lot of minutes during that time included high scorers like George Gervin, World Free, Darrell Griffith, none known for their defense.
Just out of curiosity, if 1 of those 3 SGs had played those 16483 minutes for Milwaukee instead of Moncrief over those 6 seasons, how much worse of a defensive team do you think the Bucks would have been? Still the best? 2nd or 3rd best?
Or more like 15th-20th best (4th-9th worst)? FYI there were only 23 teams at the time.
