Career Defensive Win Shares Definition - Defensive Rating (available since the 1977-78 season in the NBA); for players and teams it is points allowed per 100 posessions.

 Defensive Rating - A metric that estimates the number of wins a player produces for his team due to his defensive ability. This number is generally calculated using full-season statistics.

Small Forwards

1. Scottie Pippen - SPG: 2.0 BPG: 0.8 Defensive First Team: 8 Defensive Second Team: 2 Career Defensive Win Share: 67.3 (16^th of all time) Defensive Rating:
101.51 (66^th of all time) Defensive Player of the Year Award: 0

Scottie Pippen, without doubt, is the greatest small forward defender of all time to me. Phil Jackson commented once on his defense, "The other thing that I
remember probably most about Scottie was a sequence which he had to direct the
defense. Scottie was our voice on defense. He had, as you can tell, a
tremendous voice." That just how great Scottie Pippen was on defense.

2. Metta World Peace - SPG: 1.9 BPG: 0.6 Defensive First Team: 2 Defensive Second Team: 2 Career Defensive Win Share: 37.8 (97^th of all time) Defensive Rating:
102.92 (106^th of all time) Defensive Player of the Year - 1

Metta World Peace and Bruce Bowen are so close to each other. Deciding between the
two took me 30 minutes. That's second longest behind Frazier and Payton. I'm
okay with Bowen going here but I put Metta here for one reason: He's one the
Defensive Player of the Year Award. Bowen's only been on the defensive first
team 3 more times and one Defensive Player of the Year Award is worth 5
defensive first team selections to me. Metta has been able to hold any star.
Kevin Durant shot only 35% against Metta and 5 points below his normal PPG.
This is just one example of Metta's amazing defense.

3. Bruce Bowen - SPG: 0.8 BPG: 0.4 Defensive First Team: 5 Defensive Second Team: 3 Career
Defensive Win Share: 33.5 (131^st of all time) Defensive Rating:
102.25 (85^th of all time) Defensive Player of the Year: 0

 Bruce Bowen was one of the key parts of the Spurs success in their championships run.
He could hold Kobe, Lebron, Dwyane, and pretty much anybody he wanted. Bruce
Bowen guarded everyone on the court. He could guard Chris Paul one night and
Dirk Nowitzki the next. He was just a great defender.

4. Lebron James - SPG: 1.7 BPG: 0.8 Defensive First team: 4 Defensive  Second Team: 0
Career Defensive Win Share: 43.1 (66^th of all time) Defensive
Rating: 101.94 (75^th of all time) Defensive Player of the Year
Award: 0

I truly believe Lebron is the fourth greatest defender at his position. He's    known for his thundering dunks and scoring
ability but his defensive ability is often overlooked. He has to go out and
guard Carmelo, Durant, Pierce, and Kobe on a nightly basis. He still gets put
at the defensive first team 4 times. Oh ya, 4 STRAIGHT times. I'm not expecting
that to change any time soon.

5. Bobby Jones - SPG: 1.5 BPG: 1.4 Defensive First Team: 8 Defensive Second Team: 1 Career
Defensive Win Share: 43.2 (70^th of all time) Defensive Rating: 99.37
(25^th of all time) Defensive Player of the Year Award: (Didn't exist
until 1983.)

Bobby Jones was a true hustle player. That's what defense is all about really, hustle
and determination. Bobby would steal the ball and jump out bounds to throw it
back in to start a fast break. Jones once said in an interview, "I don't care
about points that much. I want to see my steals and blocks go up."

Power Forwards

1. Dennis Rodman - SPG: 0.7 BPG: 0.6 Defensive First Team: 7 Defensive Second Team: 1 Career Defensive Win Share: 54.5 (32^nd of all time) Defensive Rating:
100.26 (36^th of all time)Defensive Player of the Year: 2

Dennis, the Menace, Rodman was a fabulous defender.
He could guard David Robinson one night and Michael Jordan the next. Dennis was
possibly the most versatile defender of all time. He could stop you in the post
and stop somebody else from driving. Many people would Duncan here but Rodman
was a better one on one defender and a more versatile defender. Duncan was a
better team defender though.

2. Tim Duncan - SPG: 0.7 BPG: 2.2 Defensive First Team: 8 Defensive Second Team: 5 Career
Defensive Win Share: 88.6 (6^th of all time) Defensive Rating: 95.4
(2^nd of all time) Defensive Player of the Year: 0

Mr. Fundamental was a great defender. He's still a very good defender but not like
he was 5 years ago. Duncan now owns the record for most blocked shots in his
career. This doesn't even tell the whole story though. Tim Duncan was such a
good team defender. He scared everybody from coming to the middle because he
was so good at help defense. Mr. Fundamental sure was/is a great defender.

3. Kevin Garnett - SPG: 1.3 BPG: 1.5 Defensive First Team: 9 Defensive Second Team: 2 Career Defensive Win Share: 83.5 (8^th of all time) Defensive Rating: 98.95 (19^th
of all time) Defensive Player of the Year: 1

KG was/is one of the scariest players you could ever
face. He trash talks and most people hate him. Tim Duncan even said he hates
him. Garnett is more than just trash talking though. He plays lockdown defense
and stops almost anyone who comes into the paint.  Avery Bradley once commented on KG's defense, "Not taking anything away from Dwight, he's an excellent defender too, but I'm
here every day watching the things that KG does and he's just amazing." You can
hate him all you want, but you can't say KG isn't a great defender.

4. Dave Debusschere - SPG: 0.9 (NBA started recording steals in his last year) BPG: 0.5 (NBA
started recording steals in his last year) Defensive First Team: 6 (NBA started
recording this after his first 6 years) Defensive Second Team: 0 Career
Defensive Win Share: 47.7 (49^th of all time) Defensive Rating:
(Didn't exist until 1978) Defensive Player of the Year: (Didn't Exist until
1983)

This ranking can be hard to decide. We don't know his SPG or BPG until he was out of
his prime. We don't know how many times he would've been selected to All
Defensive Team's, because they started it when he was out of his prime. We
don't know a lot of things. We just have to decide by him being selected to the
All NBA Defensive First Team 6 straight years (when he was out of his prime),
highlights, and people who saw him. Red Holzman can do some clarifying for us: "Sometimes he'll score only 4 or 6 points in 40 minutes," Red Holzman told Newsday.
"People say to me: How come you play him so long? I say because he does a
hell of a rebounding job for us, a hell of a job on defense for us."That's
just how great Dave was on defense.

5. Kevin McHale - SPG: 0.4 BPG: 1.7 Defensive First Team: 3 Defensive Second Team: 3 Career
Defensive Win Share: 37.06 (104^th of all time) Defensive Rating:
105.8 (245^th of all time) Defensive Player of the Year: 0

Kevin McHale is known for his unstoppable post moves
but his defensive abilities are often overlooked. His long arms and height
could be very hard to just get a shot off. Charles Barkley even said, "Kevin McHale's
the best player I played against because he was unstoppable offensively, and he
gave me nightmares on defense." Kevin McHale sure was good.

Centers

 1. Bill Russell - SPG: (Wasn't recorded until 1974) BPG: Wasn't recorded until 1974) Defensive
First Team: (Wasn't used until 1969) Defensive Second Team: (Wasn't recorded
until 1969) Career Defensive Win Shares: 133.6 (1^st of all time)
Defensive Rating: (Wasn't used until 1978) Defensive Player of the Year: (Didn't
exist until 1983)

Like Dave Debusschere, we have to rely on career defensive win share, highlights,
and comments from opponents, teammates, and people who saw him play. Most people,
including me, think Russell is the greatest defensive force of all time. Tom
Heinsohn, one of Russell's teammates, said, "He took defensive basketball and
made it an art form." Bill Russell is definitely the greatest defender ever.

2. Hakeem Olajuwon - SPG: 1.7 BPG: 3.1 Defensive First Team: 5 Defensive Second Team: 4 Career Defensive Win Share: 94.5 (3^rd of all time) Defensive Rating: 97.9
(13^th of all time) Defensive Player of the Year: 2

Hakeem Olajuwon is amazing. He's a great scorer, rebounder, teammate, winner, and most
of all, defense. He holds the record for most blocks of all time and it looks like
this will stay for a while. It's amazing that he was able to get selected to 5
defensive first teams against Ewing, Robinson, Dikembe, and Alonzo Mourning.
Hakeem Olajuwon sure was great.

3. Ben Wallace - SPG: 1.3 BPG: 2.0 Defensive First Team: 5 Defensive Second Team: 1 Career
Defensive Win Share: 70.6 (14^th of all time) Defensive Rating: 95.8
(5^th of all time) Defensive Player of the Year: 4

This selection was definitely the hardest one to decide. I had to choose between Kareem,
David Robinson, Nate Thurmond, Dikembe, Alonzo Mourning, or Ben Wallace. In the
end I chose Wallace because he won 4 DPY's (tied for most with Dikembe), had
the 5^th highest defensive rating ever (Only David R. is better
between the 7 players listed before), and has been selected to 6 defensive
teams. In my opinion someone who wins 4 DPY's definitely should be in the top 5
in any debate about who's the greatest defender of all time. All in all, I believe
Big Ben is the 3^rd best defensive center ever.

4. Dikembe Mutombo - SPG: 0.4 BPG: 2.8 Defensive First Team: 3 Defensive Second Team: 3 Career Defensive Win Share: 68.5 (15^th of all time) Defensive Rating: 99.2
(23^rd of all time) Defensive Player of the Year: 4

Dikembe Mutombo is one of the greatest shot blockers of all time. How else could a
center start if he only averages 9.8 PPG for his career? The 4 DPY's also
explain to me that he definitely has to be in the top 5 for this category. His
finger wag shows how much confidence and arrogance he possessed. Dikembe was
really an amazing defender.

5. David Robinson -SPG: 1.4 BPG: 3.0 Defensive First Team: 4 Defensive Second Team: Career
Defensive Win Share: 80.1 (10^th of all time) Defensive Rating: 95.6 (4^th of all time) Defensive Player of the Year: 1

David Robinson is very underrated when it comes to defense. He was known for scoring
and rebounding but his defense gets overlooked sometimes. His defensive rating
and win shares can't be ignored and winning a DPY over Hakeem, Ewing, and many
others proves he was great. D-Rob was definitely special.

People who barely missed the cut:

PG's: Maurice Cheeks and Norm Van Lier

SG's: Joe Dumars and Alvin Robertson

SF's: Larry Bird and Grant Hill

PF's: Rasheed Wallace and Karl Malone

C's: Kareem Abdul Jabbar, Alonzo Mourning, Nate Thurmond, Wilt Chamberlain, Mark Eaton, Dwight Howard, and Patrick Ewing.
