Here's an interesting discussion about why Paschall regressed for the Warriors last year:
What's Paschall's ideal role in Golden State and is he ready to fulfill it?

One of the takeaways is that he does best in P&R and isolation situations. With Draymond and Steph back last year, neither of those two types of plays is prominent for Warriors. Maybe it will be better for Jazz?
Also thought it was interesting just poking around how many pre-draft prognosticators thought of him as a versatile, capable, energetic (if still imperfect) defender. Warriors were excellent on defense last year, so I'm not entirely sure why the defense seems to have stagnated/regressed for him.
