Beyond the fact that I personally don’t think he’s capable of playing in a fluid offense, he’s got issues that aren’t X’s and O’s
The biggest issues with him are personality traits. He’s lazy and impatient. The minute he doesn’t have it, or things get hard, he crumbles.
I can forgive a lot. there is way too much footage of him just mailing plays in. Giving up on plays. Walking back on defense. That’s the stuff that’s cancerous. You can’t let that stuff go.
Again he was part of a pretty fluid offense until injuring his ankle and was hugely efficient in a very fluid offense with the Pels.
To your other point, there are also a ton of plays where Julius busts his ass to double/trap guys on the perimeter, closing out aggressively, battling for offensive boards with multiple guys, etc.
...and a lot of those compilations of Randle's "lazy plays" include a lot of plays where Randle "gets blown by" because he's sticking to his assignment and can't hedge further without conceding the corner 3.
Sure Mitch can help on those plays without it being a problem, but Mitch is a special defender, Mitch's guy is seldom a dangerous 3pt shooter, and we can afford Mitch picking up fouls on the defensive end a lot more than we can Julius or Jalen.
Speaking of whom, compare Julius to Brunson. Brunson is just as "lazy" against the Ball and he doesn't make anywhere near the defensive impact that Julius does; whether when they're dialed in or in general.
But nobody complains about Brunson pacing himself and being selective with what fouls to take because we typically accept that from guys who carry that kind of offensive burden.
...despite the team having a much better kid sitting behind Brunson than we do sitting behind Randle.
And our coach is Thibs, can you imagine an NBA coach less likely to just let that kind of s*** go if it was as cancerous as you're implying? This is the guy who brought Jimmy in to try and bully KAT/Wiggins into busting their asses.
That guy is in love with Randle despite Julius being as lazy as people try to make him out to be? I find that to be a hard sell.
