It seems like you know your NFL. I want to argue with you but I know I'm biased and I know I really don't know WTF i'm talking about. From the limited NFL I have watched and many of his games in college I don't see how Hurts is any better (I think Purdy's instincts escaping/extending plays are much closer to Mahomes than they are to Hurts). The other four I do see some things you're talking about.
With our other superstar Tyrese he genuinely is the best playmaking point guard with clear separation (not talking about small shooting guards like Steph). It drops down to guys like Fred VanVleet, Lamelo Ball and Cade Cunningham after him. If you're looking for a Magic Johnson or Steve Nash superstar passing guard he is it. If you tiered him out with all positions I'd go
Tier 1: Jokic is tier of his own, only player I've ever seen get boring average effort triple doubles
Tier 2: Embiid, Gianis
Tier 3: Luka, Steph, maaaaaybe Hailburton (notice those are the first Americans)
Tier 4: about 12 players and Haliburton is in there for sure
I debated on Hurts, I went with tier 2 mostly because he's been to a super bowl but he's right on that 2/3 line you can make an argument either way on and I wouldn't disagree with someone's opinion if they had him down a tier.
I used to follow the NBA as a big Bulls fan growing up but I have basically lost interest in it over the years. Last time I maybe even remotely cared to watch some games was during the Rose era so probably over 10 years now since I cared to pay much attention to the league. I couldn't do a ranking or tiers at this point.
