I personally don't see Erving as a clone of LeBron, or so close that "if I voted for LeBron, I have to vote Erving next"...but I do actually somewhat feel like that about Walton in comparison to Hakeem/Duncan/Garnett...and I personally would have gone with those 3 in some order for the last 3 spots
(+ others many times said that Walton’s impact on defense was GOAT level)
I don’t agree with that and the more closely I look at Walton, the more I think he is slightly overrated.

So based on pure with/without data Blazers defense was better with Walton by -4.9 ppg in 1977 and -3.9 in 1978. Overall -3.8 over these two seasons, and sample is really big, because we have 42 games without Walton.
Of course these result aren’t pace adjusted and that’s the problem. It’s very probable that Blazers played faster with Walton than without him. The only question is how much faster exactly? I have hundreds of with/without players seasons in my data base and the biggest increase in pace without given player is +5.1 (Reggie 1996, 6 games without). Then Price 1989 (7 games w/o), KG 2006 (6) and Price 1995 (34) with +4.1 each.
Among players similar to Walton I have Gasol 2008 (55 games w/o) and Lakers with him played slower than without Pau. The same with Grizzlies 2008 (-2.2). Vareajo 2011 (51 games w/o) also made Cavs play slower (-0.4) and -2.4 in 2008 (34 games w/o) . NYK 1987 also played slightly slower with Ewing (-0.7, 32 games w/o), but in 1998 they played faster with him (+4.0, 55 games w/o). Gasol 2005 (26 games w/o) and Hakeem 1991 (26) are also examples when teams played faster with their star big man, but not much faster: +1.0 each. Similar story with KG 2009 (25 games w/o, +0.1 faster pace) and so on.
So it’s rather unreasonable to assume 77-78 Blazers with Walton would play faster than 2-3 possessions per game. (more reasonable is assumption that pace wouldn't change or would be slower WITH Bill) So lets look how PTB drtg would look like if we assume they pace was slower by 2 possessions without Walton.
In 1977 Blazers pace was 108 and -1.5 drtg (relatively to league average). Assuming 110 pace with Walton PTB drtg during 64 games with Bill was -4.0 and +9.5 in 18 games without him.
In 1978 Blazers pace was 104,2 and -3,7 drtg. Assuming 106,2 pace with Walton Blazers drtg was -6.4 with him and +4.0 without.
So it looks like he transformed the worst defense in the league into the best. But were Blazers really that bad defensively without Walton? In 1979 Blazers drtg was -0.7, so still better than average, despite the fact Walton didn’t play at all and Lucas with Hollins missed many games.
And when we look at Blazers drtg in 77 and 78 with/without Walton without assumption that pace changed we would see that:
1977: -2.2 with, +2.4 without
1978: -7.9 with, -4.3 without
So these results without assumption about changing pace are much more consistent with what happened in 1979. So without a doubt Walton’s impact on defense was positive, but in no way it was GOAT level. For example we all know Russell lifted average, or slightly above average defensive team to -10 drtg during his peak. That’s GOAT level impact. Or 2009 KG +1.2 drtg team (25 games w/o KG, pace slower by 0,1) lifted to -8.1. Or Duncan 2004: from -3.5 (13 games w/o, pace faster by 1.0) to -9.0. Or 2005 Duncan: from -1.1 (16 games w/o, pace faster by 0.9) to -8.0. Or 1992 DRob: from +2.6 (14 games w/o, pace slower by 1.6) to -5.0 drtg. Walton’s defensive impact seems like tier below these 4 players who really had GOAT level defensive impact.
I'd actually love to see this addressed by some of the other panelists, but on the other hand...is it damning either way? If If the impact was huge and the question is just whether that influence was more on offense than defense...couldn't the response be "so what"? I had a similar reaction last year in a discussion about Jason Kidd...if the overall impact is there, I don't know that it matters so much which side of the ball that influence is on.
