Although he never made an All-D team Bo did get some DPOY votes in '96, '98, and '00. He came off the bench most of the time and rarely averaged more than 30 minutes per game. I'm sure that was a big factor in his lack of defensive accolades. Starters played more minutes back then.
His defensive box-score numbers were fantastic. Extremely impressive block and steal rates for a versatile, undersized guy playing all three front-court positions. DBPM is right up there; he led the league one season.
He finished fifth in DPOY when he got 36.0 mpg in 1997-98. But his best defensive seasons are probably either 1996-97 or 1999-00. Both years have some wild discrepancies between his on/off numbers and his teammates. Here's how a RealGM poster detailed his '97 season:
LA Bird wrote:Peak Outlaw at 23. Haven't ranked Ratliff yet but he is probably around top 60.
Outlaw is one of the most underrated defensive players ever. He was among the league leaders in defensive RAPM in the late 90s with Mutombo / Robinson and not even the RAPM supporters on this board seem to notice. Outlaw's career defensive on-off post 2001 in his 30s is -5.8 in the regular season and -8.0 in playoffs - limited minutes but those are absolutely elite numbers.
In 1997 when he led the league in NPI defensive RAPM, here is how his on/off compares to his teammates on the Clippers...
Net On/Off
+15.6 Bo Outlaw
-0.8 Rodney Rogers
-1.2 Lorenzen Wright
-12.7 Malik Sealy
-15.9 Loy Vaught
Defensive On/Off
-11.4 Bo Outlaw
+2.8 Lorenzen Wright
+2.9 Rodney Rogers
+4.8 Malik Sealy
+9.3 Loy Vaught
* Estimates based off NBA.com on-court net ratings
Outlaw left in free agency and the Clippers started the next season 1-11 with a league worst +12.5 defense before Vaught (their worst defender who gets all the credit because of better box score) had a season-ending injury. Even without Vaught, Clippers still suffered a massive blow without Outlaw and ended with a bottom +6 defense for the next few years. Outlaw had huge defensive impact and it's a shame he never got the recognition he deserved for carrying that pathetic team to an on court -3.9 D.
That Clippers team won 36 games and made the playoffs in a weak conference with a very forgettable cast of players coached by Bill Fitch.
The 1999-00 Orlando Magic were projected to be the worst team in the NBA. They had lost their three highest-minute players Penny Hardaway, Nick Anderson, and Horace Grant. With a rookie coach (Doc Rivers), they would go on to win 41 games and narrowly miss the playoffs in a season dubbed "Heart and Hustle."
The play-by-play data is similar to 1996-97:
Net On/Off
+13.1 Bo Outlaw
+1.4 Ben Wallace
-2.4 Darrell Armstrong
-0.1 John Amaechi
-1.4 Chucky Atkins
Defensive On/Off
-9.4 Bo Outlaw
-5.0 Ben Wallace
-1.4 Darrell Armstrong
-1.3 John Amaechi
+4.1 Chucky Atkins
Bo had that team at a 97.6 DRtg when he was on the court. That would be the equivalent of playing 0.6 points better than the top-ranked 98.2 DRtg Lakers defense that season. League average ORtg was 104.1 so that on-court DRtg was like -6.5 rDRtg.
And it wasn't like Bo wasn't playing much: 2,313 minutes. Only Armstrong was on the court more.
Pretty remarkable stuff.
If you dive deeper into the play-by-play data/lineup numbers, you notice that his defensive impact is coming from his ability to lower the opponent's eFG% and FTr while increasing their TOV%. He's not adding value by impacting team defensive rebounding/limiting opponent second-chance points.
Here's a look at his RAPM defensive four factors:

The position you play is going to generally determine what kind of impact you'll have on defense. Guards and wings tend to generate more turnovers for instance. PFs and Cs will usually have a greater influence on lowering opponent shooting percentages and free-throw rates while improving team defensive rebounding.
But the lines do get blurred and there are outliers. Versatile defenders who can defend several positions often have hybrid qualities. Hakeem, Garnett, Ben Wallace, and Draymond have guard-like steal rates and lineups featuring them generate turnovers likewise. Bo Outlaw falls into this category.
His positional outlier quality is his turnover generation. Basketball Reference has him as playing SF 33%, PF 54%, and C 14% of the time over his career (data only going back to '97.) He played slightly more SF (34%/52%/14%) in his best years from '97 to '04.
His position can be graded out to a 3.8 average. This compares very favorably to Josh Smith (3.8), Draymond (3.9), Garnett (4.2), Rasheed Wallace (4.3), Robert Horry (3.9), Luc Mbah a Moute (3.6), Giannis (3.7), Kenyon Martin (4.2), Lamar Odom (3.8), Andrei Kirilenko (3.3), Shawn Marion (3.3), Robert Covington (3.5), Herbert Jones (3.7), and Justice Winslow (3.4).
Era is obviously a factor here.
Of all players in the 28-year RAPM database from a 3.3 to a 4.3 positional average, no one has a greater DTOV than Bo Outlaw. Meaning, that no one's presence on-court results in as many opponent turnovers.
Robert Covington and Thaddeus Young are the closest. Otto Porter Jr, Kirilenko, and Draymond aren't that far off.
Hell, including every player/all 5 positions he's still 15th. 7th for 2.0 to 5.0.
But once you cross reference that with lineup impact on opponent eFG%, that's when things become clear. The only 3.3-4.3 guys in the same ballpark for overall defensive impact (D-RAPM), defensive influence on eFG% (DEFG%), and turnover generation (DTOV%) are Draymond Green and Kevin Garnett. With Robert Horry a little ways off.

Anyways. This is getting a bit long so I'll end it here. But Bo Outlaw was a hell of a defender. He looks a lot like Draymond Green on defense per the numbers.
