Bobby Dodd didn't get 'overconfident' as much as he got arrogant. You see his arrogant attitude in his followers to this day. The whole 'we may not be winning but we are doing it the right way; everyone else is unethical and not as holy as us'. You don't refuse to play games in Mississippi because you are overconfident. You don't take your ball and leave when you don't get your way either.
If you really think GT would have become Vanderbilt if we stayed in the SEC, or that FSU and Clemson will be like Mississippi State in the SEC then that's really all we
This is why most of the arguments and freakoutery are stupid and based on ridiculous speculative hyperbole - statements like this:
"Ten years after college football's map was drawn and redrawn amid massive realignment, the Longhorns and Sooners have the potential to usher in a brand-new landscape defined by 16-team behemoth conferences that ignore geography, history and rivalry in chase of larger and larger television contracts."
Geography? The SEC is already in Texas. Texas is adjacent to Arkansas and Louisiana. Oklahoma is adjacent to Texas, Arkansas, and Missouri. It's nothing like a geographic hopscotch.
Rivalry? Not a single major rivalry is sacrificed under almost every speculative plan. On the contrary Texas gets to play Arkansas again, and aTm gets UT back whether they want it or not. Oklahoma can continue to play Oklahoma State OOC just like the SEC-ACC rivalries. The minor rivalries LSU has with Bama and UF might become less frequent but those aren't really that important. Tennessee will still get Alabama every year. Georgia is still going to play Auburn. None of that changes. That's part of what makes what the SEC has done so smart. They don't sacrifice history and they don't sacrifice tradition and rivalry.
History? Ok maybe, but if nothing else the Big 12 has been a stitched together entity since the demise of the Southwest Conference. I mean unless you really care about those great intrastate rivalries with Baylor and TCU and TTU. Hell I'm sure there are a few in Texas who shed a tear that Rice vs. SMU doesn't mean as much anymore.
Here's an expansion plan for the ACC.
Just wait a few years and take the teams that get kicked out of the SEC. Pretty soon they'll start wondering why Alabama and Texas aren't getting more money than Vanderbilt and South Carolina.
