As far as I can tell, aTm at best is a place where coaches coach before they go coach national championship teams somewhere else. 😎
I’m not sure if you’re serious, or you just omitted blue font.
Jimbo  89-45 without Jameis. Other than 2020, abysmal record against the P-5, on the road in the SEC, in games against Top 20 teams. The list goes on.
Leads the nation in recruiting rankings and is perpetually 8-4. At best. Several losing seasons sprinkled in his record.
Sumlin  beat us the week after an emotional LSU win, on multiple Heisman moments / divine intervention in favor of Johnny Manziel. Parlayed that into generational money in buyouts after being fired from aTm and Arizona.
Mike Sherman? Dennis Franchione? RC Slocum? Jackie Sherrill? Tom Wilson (had to look that one up)? Emory Bellard?
You got me on Stallings and Bryant, but Stallings was fired from aTm over 50 years ago, and Bryant left almost 70 years ago.
aTm isn't a steppingstone to future success.....it's where coaching careers go to die.
Booster / NIL money? Recruiting territory? Facilities? Ability to pay coaches (stifle laughter here)? Any tangible advantage you might name? They have all of them. They’ve had all of them for 100 years.
Even with Manziel, they still lost 2 games, then 4, then 5.
They’ll have the occasional 10-win season. They win nothing that matters.
