1. There's almost no "success stories" regarding star players and the GL because top draft picks, who by a WIDE margin are the ones who end up becoming stars, simply skip the GL altogether. This is because they come into the league with a sufficiently high floor and physical development to contribute, and bang, straight away (think LeBron, Luka, et al, they don't need to "grow into" their bodies nor develop basic aspects of their games; if they did, they wouldn't get picked top 3). Primo isn't that. And while I'm fully aboard the Primo wagon and think he can be a significant contributor to the league... LeBron, Luka level? Yeah, not quite. As you said, there's many players like KAT who were
hindered by getting thrown into the fire - why is the argument not made that the GL could've helped them instead? I wonder...
2. I don't think Primo playing in Austin means he's too far away from Pop to get coached, TBQH. Firstly, now more than ever, everyone's connected - a Zoom away. Secondly, Primo both attends Spurs practices and Spurs games now, so he's getting coached alright. There's also developmental staff following him throughout practices and into Austin games, it's not like Pop is the be-all, end-all of coaching/development. Thirdly, well, I'm of the opinion that the modern NBA has passed Pop by a bit... Not sure I want him telling Primo that 3's are overrated too much

. But that's beside the point.

Disagree. Matter-of-fact, when we bring in Primo to the Spurs, we're playing him in exactly the role he's been accustomed his whole life, which is a major part of my argument. His lone season of college was spent playing off-ball, C&S style behind "more talented" on-ball players, which is exactly what he does when he spots up in the corner as DJ does his midrange pullups. On the contrary, down in Austin, he develops into an entirely different, ball-dominant game, which he's shown much potential and adeption for, so these reps are meaningful; I'd actually wager that, given these cir stances, Primo can make better use of Austin than most assignees, who mostly go down to work on just a specific part of their game. Above all, Primo needs reps... Which is why I'm very glad that he's playing both Austin AND Spurs. Lastly, Kawhi was an entirely different bodytype, player type, and previous-experience-to-the-NBA type, not very comparable. Had Primo been Mr California twice or some like that, he might've been brought up differently, who knows?
4. Ahh, this one I agree on. Zero reason for Forbes to play, especially if he's not gonna get traded (as we all know). Definitely blame Pop for this one. But still, it's not exactly like Primo is the only other option at SG... Lonnie or Devin or whomever could soak up those minutes, too, just saying. But yeah, less Forbes
por favor. But also - you do know Primo played like 40 minutes two games ago, right? Lol. That's exactly what I'm saying.... Austin
and Spurs, please!
