If you will notice the GM of the Rams, Les Snead, and the GM of the 49ers, Jon Lynch, are both in their 50's.
So, while there are coaches that trend younger - unlike baseball you don't see too many 35 year old GM's in the NFL.
Smith was the Director of College Scouting here and then VP for Player Personnel for Ron for 1 year.
I don't know about the rest of you, but when I was building my resume I very rarely got a second promotion that quickly after the first, unless someone else departed where I was working and I had the chance to prove myself in a 'stretch' assignment.
Smith to date has no record making trades in the NFL, he has no experience negotiating contracts or managing the interplay between salary cap and roster composition, nor does he have much if any experience dealing with the media.
In other words, he has learned about 50% of the job most GMs perform for their organizations.
But he has experience mocking the draft with the scouts and help setting the final board for the War Room picks.
Sounds like a VP of Player Personnel to me.
As a boss of mine used to say, don't ask for more until you have gone out of your way to DO MORE.
