Per BON:
Athletics director Steve Patterson is fond of referring to the university as an international brand and has made the promotion of that brand a clear imperative, as the men's basketball team will open the 2015-16 season against the Washington Huskies in Japan.
Potential plans to play a football game in Mexico City never panned out for Patterson, apparently because of some donor backlash against the idea, but Dubai has a been a possibility for some time after Patterson discussed his future plans with ESPN last fall:
"We have a lot of folks in the oil and gas industry," Patterson said. "Houston is the center of the world in terms of the gas industry. A lot of those alums spend time in the Middle East, and Dubai is a place that wants to use sports to help put itself on the map. So we'll have some conversations, and we'll see where they lead."
Now those conversations are starting to happen in earnest, with Mack Brown as the ambassador for the school doing what he does best -- glad-handing with alums (read: donors and potential donors) and in general using his political charm to benefit the university.
Potential impediments to the game include finding a suitable stadium, the time difference, and the scorching September temperatures in Dubai. As for potential opponents, the Chat Sports report mentioned Notre Dame, Ohio State, LSU, Army, and Navy.
