So much buthurt and/or ignorance of the current state of affairs. A&M isn't an "elite" school but it's certainly top 10-15. ANd just because a school had success in the past doesn't mean they will continue to.
Which of those schools you mentioned are currently "elite"?
Oklahoma - recruiting is dying a slow death. Their heyday is when they were cherry picking the top talent in Texas. They've been steadily declining the past 5 years and just last year, as co-champs, got destroyed by A&M. They are not fighting for recruits against Baylor and TCU.
UT - One NC during the Mack Brown era. One. UT is mainly considered "elite" because of MONEY. They can and will likely have to money whip a coach to bring them in, especially with all the turmoil and quick turnaround the fans and boosters will expect and demand.
Notre Dame - had one great year (2012) and two good years since Lou Holtz left in 1996. Been through 4 head coaches during that time as well. Brian Kelly wasn't their first choice either.
USC - Had a great run under Pete Carroll but even that was marred by cheating and other scandals. Is currently under sanctions and the roster and recruiting is frankly a dumpster fire. Will take a lot of cash to bring in a big name head coach to try to turn around the mess. Not really a "destination job" currently, though it could be with the right coach.
Alabama - Yes, this is a legit "elite" school right now.
A&M is a hot team right now and broke fundraising records this past fiscal year. Plus, with the additional cash expected to come from the SEC Network starting in 2014, you can expect A&M to be able to match any offer short of a Texas or Ohio State.
And, like I've said, people close to Sumlin have said that he and his family loves A&M and College Station and the lifestyle there and he wants to stay awhile and build the program. He has tons of in-roads and contacts in HS in Texas and LA. And he's the best college coach for the best team in Texas playing in the best conference in the country. He may leave eventually and his agent will probably use USC to get another raise for him (deservedly). But USC isn't currently a better job for him and I'm betting he won't leave.
