I'm of course not going to say Jeanty is a must-pick at 9, but I wouldn't be surprised if they took him.
Moore got to the Cowboys in 2018 so inherited Zeke in his early prime (yes, they had rebuilt the line by then with Zack and Tyron).
Moore had Barkley.
Moore only had 3rd down back Ekeler as the feature back in 2023 in LA, and they under-achieved.
Jeanty is averaging pick 12 (Cowboys) in the mocks composites so it would not be a reach.
A backfield anchored by Kamara the elder and Jeanty the future would be stout, and give the offense a new identity. Rattler-Jeanty could be a launchpoint.
While not relevant to today, the 1980 Saints took George Rogers 1st to rebuild from the 1-15 team. The 1986 Saints took Reuben Mayes in the 3rd round and featured him immediately starting in his rookie season.
I wanted a young offensive head coach and we got him and he wants to establish the run. I would be fine with Jeanty unless things come up that lower his draft stock, or, as you said, we'll see what they do with roster and FA before the draft. I hope CE-H has his body and mind straight and would be a 3rd back, but we'll see about all that.
A good coach should be able to get weapons and build O-Line at the same time, and assuredly over this and next offseason.
