Texas A&M had the last laugh on Sunday, writes ESPN.com's Ivan Maisel. After a century or so of being disrespected, teased, mocked and scorned, the Aggies had enough. How else to explain that the school would leave all that it left behind?

The Aggies are McFly in "Back to the Future," Private Pyle in "Full Metal Jacket." They snapped. Texas A&M partisans and everyone else who believes that Texas got too big for its hand-tooled boots will argue about whom to blame for as long as Reveille barks at Bevo. But the Aggies are leaving a Big 12 that's not all that different from the conference they agreed to stand by 15 months ago.

They were no more an equal partner to Texas in 2011 than they were in 2010. But the dispute over the ESPN-operated Longhorn Network served as the last bruise to Aggie Pride.
