The rich kid narrative is funny to me.
Johnny Manziel is an entitled brat because he just is. He likes the fame, celebrity, and partying.
The reason Josh Rosen hasn't made it not because he's spoiled and rich. He hasn't made it because A) he's been in bad situations (talent poor Cardinals before Kingsbury, talent poor Dolphins before Flores) or B) he's just not that good.
Peyton Manning outworked (in the film room) every one of his teammates.
Patrick Mahomes any good? His dad made over $2M in his MLB career.
Steve Young (great grandson of Brigham Young), Hall of Famer.
John Elway (his father was a D1 Head Coach), Hall of Famer.
Eli Manning (son of Archie) , 2 Super Bowls.
Nick Foles (his father owns Eddie Vs restaurants), ehh overall but Super Bowl MVP.
Andrew Luck (father is former NFL player Oliver who has a net worth of $10M), pretty good minus the injuries.
All came from money.
If you look at a lot of quarterbacks, they come from affluent families. QB guru's, and almost all these kids have them now, are not cheap.
I say again, Zach will be fine. And if he somehow isn't, it most likely won't be because of his family's money.
