I think a dynamic that is fairly true of all prospect evaluators is also uniquely unkind to the Cubs in this specific cycle. For all the refinement in scouting over the years and increased data at our finger tips, you're still going to see large variance with players at lower levels, and players may have flaws that simply cannot manifest themselves at those levels due to the quality of competition. So prospects with no other track record who wreck shop can get the benefit of the doubt because some of those flaws haven't yet come to fruition, so they might not! The inverse works with players at higher levels, especially those with 3-4 MiLB seasons under their belt. They've been exposed to both the time and quality of competition to see those flaws and to create educated skepticism about their ceiling and MLB futures.
Now think about this dynamic in the context of the Cubs' top prospects as well as those they've traded away in the last 12 months. The shiny new toys are mostly those who are no longer in the system(Hope, Smith, Ferris to a lesser extent), while the remaining top prospects are those with several years and levels to build up skepticism(Caissie, Alcantara, Triantos, Ballesteros). Shaw is the closest to splitting the difference of great performance at high levels without much track record of imperfection, and as a result he's far and away the #1 ranked prospect in the system.
This time next year it could be the inverse, you might see a chunk of that AAA cohort graduated or traded, a few 2024 draftees break out(Mathis? Southisene?), maybe next year's 1st round pick pulls a Shaw/Smith, and the story may be 'the Cubs graduated 4 Top 100 prospects and they're ranked just as good as last year'.
