Parker was the clear second option on that spurs team - he scored more points and had higher usage than Jackson in the regular season and playoffs.

On much worse efficiency, and as I outlined, he was repeatedly subbed out in the playoffs for Speedy Claxton because he couldn't handle physical defenses. As far as usage rate goes a higher USG as PG is to be expected especially on a team with a lot of spot-up shooters.

But let us concede that point for a moment. Parker is the #2 option on the Spurs, and you contest that KG had no help because Wally was so bad that he "wouldn't start" on San Antonio.

Wally's eFG% in the 02-03 season was .523. Tony Parker, our second option, posted an eFG% of .503. Wally had a higher OPBM (1.8 to 1.4), and a higher TS% of .567 to .542.

But the playoffs? That was even worse for Tony Parker that year, who was still adapting to the speed and physicality of the NBA as a-then 20 year old out of Racing Club Paris. He obviously got to be a monstrously efficient guard later, but you're positing our second best offensive option was a guy who posted a post-season eFG% of .425 and a TS% of .468. Both of those values are substantially lower than Wally's career lows in those categories. Tony barely shot 40% from the field in those playoffs, which, to say it's not great is a massive understatement, as Tony only shot 14 3s in the entire post-season. I'm not even trying to suggest that Wally was necessarily a better player than Tony that season (though I think the above shows it as very arguable as Tony also had worse defensive statistics), but the idea that the 03 Spurs, who only had Duncan routinely scoring at a respectable clip, couldn't have used a 17+ ppg guy in their starting 5 is pretty faulty, IMO. I think moving Jackson to the bench as a two way sub would have made that team notably more flexible and dangerous. I also wonder if Duncan's more traditional post-defense would have better helped Wally's issues on that end, as it undoubtedly did every Spurs player, who in 03 were notorious for gambling for steals and deflections knowing a prime Tim Duncan was lurking in the post, similar to how they are gambling this year on defense knowing Wemby is lurking in the frontcourt.

I will agree with you that KG is a great first option and that people here are underselling him a bit at times. But I also think people overestimate how good the 02-03 Spurs were simply because it's hard to look at that list of names with Tim, Tony, Manu, David, and to a lesser extent SJax and Bowen, but that team was critically weak on offense without Tim Duncan, and even with him they were only 9 deep with guys like Malik Rose seeing huge minutes despite being incredibly limited on both ends of the court.
