So How Attractive is the Saints HC Job?

I'm sorry but talent is a major factor. You need playmakers on both sides in the NFL and don't have many/if any.

Taysom is 34 coming off a serious potential career ending if not altering injury.
Olave is our only receiver and he's coming off two concussions. He's one hit away from being out of the league.
AK is our best playmaker but he's a 30 year old RB.
Demario is old and well past his prime.
Cam is likely going to retire/ should retire.

AND our cap situation is the worse in the league.
If coaching is secondary to acquiring talent, then why do some franchises seem to perennially draft in the top ten and never improve. Whereas teams that have good coaches and draft at the back end of the draft in each round remain successful every year.
