But when it comes to the good and especially the elite defenders at the center, forward, and guard positions, the taller timber in the frontcourt tends to have a greater impact.
Right? I think most would agree on that as a general rule. I know the analytics guys would agree. After a certain point, the top end of historical defensive on/off, statistical box-derived defensive plus-minus stats, defensive RAPM, and seasonal one-number defensive metrics is populated by centers and power forwards.
Bill Russell, Hakeem Olajuwon, David Robinson, Dikembe Mutombo, Alonzo Mourning, Kevin Garnett, Tim Duncan, Ben Wallace, Dwight Howard, Rudy Gobert, etc. These are the names we'll see first and foremost. The cream of the crop defensively. Missing a few names but that more or less covers the big hitters on defense according to the numbers.
But what if I proposed to you this question: Can an elite defensive PG impact defense as much as an elite defensive center?
What would your response be? I know, "elite defensive PG" and "elite defensive center" are vague denominations. Am I talking about those guys listed above? Or your typical elite-but-not-all-time defensive centers? Honestly, I'm not sure. But this is a question I want to pose to you, and a discussion that greatly interests me. And it's one that other posters have discussed on RealGM before.

Jason Kidd had an intriguing run through his prime of consistently elevating teams defensively. Whenever he joined those teams, they got better, and largely on defense. And when he left? The opposite happened.
When he joined New Jersey:
2000-01 Nets: 100.0 ORtg (-3.0 rORtg); 105.5 DRtg (+2.5 rDRtg); -5.5 net rating; -5.30 SRS; 26-56 W/L
2001-02 Nets: 104.0 ORtg (-0.5 rORtg); 99.5 DRtg (-5.0 rDRtg); +4.5 net rating; +3.67 SRS; 52-30 W/L
Change: +4.0 ORtg (+2.5 rORtg); -6.0 DRtg (-7.5 rDRtg); +10.0 net rating; +8.97 SRS; +26 wins
When he left Phoenix:
2000-01 Suns: 100.3 ORtg (-2.7 rORtg); 98.0 DRtg (-5.0 rDRtg); +2.4 net rating; 2.63 SRS; 51-31 W/L
2001-02 Suns: 103.3 ORtg (-1.2 rORtg); 104.0 DRtg (-0.5 rDRtg); -0.7 net rating; -0.29 SRS; 36-46 W/L
Change: -3.0 ORtg (+1.5 rORtg); +6.0 DRtg (+4.5 rDRtg); -3.1 net rating; -2.92 SRS; -15 wins
Even when he was traded halfway through the season to Phoenix, the defense improved dramatically in his first full season:
1996-97 Suns: 109.3 ORtg (+2.6 rORtg); 108.6 DRtg (+1.9 rDRtg); +0.7 net rating; 0.21 SRS; 40-42 W/L
1997-98 Suns: 107.4 ORtg (+2.4 rORtg); 101.8 DRtg (-3.2 rDRtg); +5.6 net rating; 4.44 SRS; 56-26 W/L
Change: -1.9 ORtg (-0.2 rORtg); -6.8 DRtg (-5.1 rDRtg); +4.9 net rating; +4.23 SRS; +16 wins
Pretty much all his new teams got better while his old ones got worse throughout his career. But I'll stick to these since they're the most dramatic and in his prime.
In his prime, Jason Kidd was seemingly elevating middling and mediocre defenses into elite ones. Look at these stretches from 1998-2006 and 2000-2004. Lockout year wasn't included because the numbers were funny across the league that season. Phoenix was a top-ranked offense which wasn't the norm for a prime Jason Kidd team.
1998 Suns: 101.8 DRtg (6th) [-3.2 rDRtg]
2000 Suns: 99.0 DRtg (3rd) [-5.1 rDRtg]
2001 Suns: 98.0 DRtg (2nd) [-5.0 rDRtg]
2002 Nets: 99.5 DRtg (1st) [-5.0 rDRtg]
2003 Nets: 98.1 DRtg [1st] [-5.5 rDRtg]
2004 Nets: 98.0 DRtg [4th] [-4.9 rDRtg]
2005 Nets: 103.1 DRtg (7th) [-3.0 rDRtg]
2006 Nets: 102.4 DRtg (4th) [-3.8 rDRtg]
1998 + 2000-2006: -4.44 rDRtg
2000-2004: -5.1 rDRtg
That's pretty crazy. For comparison, Nash's Phoenix teams from 2005-2010 had an average of +6.7 rORtg.
Six straight seasons of Nash = +6.7 rORtg
Five straight seasons of Kidd = -5.1 rDRtg
And I think Nash had the better-supporting casts that were not only more talented but a better fit for his skill set. I wonder what Kidd could've done with an appreciable, equal level of help that plays to his strengths. Imagine if he was in Detroit instead of Chauncey.
Ben Wallace, Rasheed Wallace, Tayshaun Prince, and Rip Hamilton feels like the same ballpark as Amar'e Stoudemire, Shawn Marion, Joe Johnson, and Quentin Richardson. Kidd probably would've had a few 60+ win, 7+ SRS seasons like Nash with that team. He adds to their strengths - defense - and what they lose in shooting they make up in playmaking.

Yes, there were injuries, younger players developing, and new players being added to Phoenix and New Jersey. But I think the defensive improvements all revolve around Jason Kidd.
Kenyon Martin was doing his thing before Kidd got there, blocking shots, accumulating steals, and playing starter minutes. Didn't help the defense all that much in 2000-01. Neither did he help Denver on defense all that much when he went there. Despite future DPOY Marcus Camby also being on the team.
Jason Collins and Richard Jefferson were rookies in 2002 who played 24.3 mpg and 18.3 mpg respectively. I'm sure they helped but I'm still leaning toward Kidd being the key to it all.
My feelings are largely the same about his defensive support in Phoenix. Marion was a nice addition like Kenyon but The Suns were strong on defense in '98 before he got there and disappointing in the years after Kidd left. I'm just not blown away.

Was Jason Kidd a generational defensive talent with an impact similar to elite defensive big men?
When I watch him, he feels in many respects like a 6'4" guard version of Garnett. While his positional qualities were elite (POA defense, getting around screens, closing out on shooters), it was his off-ball positioning, versatility, rotations, communication/quarterbacking, and defensive rebounding that set him apart. KG was a great rim protector and post-defender, but it was those other qualities I just mentioned that made him so incredible.
Naturally gifted athletes who elevated themselves on defense thanks to versatility and high basketball IQ.
