There are coaching Dooley brothers, Vince at Georgia and Bill at Virginia Tech, and now the Brown brothers at the head of separate college football programs. U. of Cincinnati hired Watson Brown, 32, yesterday, a couple of weeks since Appalachian State appointed Mack Brown. Cincinnati found its man at Vanderbilt, where he closes out as offensive coordinator with Friday's Hall of Fame Bowl; previously Brown was head coach at Austin Peay (7-4 in both '79 and '80). UC had been reclassified to I-AA by the NCAA but obtained a restraining order to remain I-A, and Brown said he had been promised before replacing Kansas-bound Mike Gottfried that the Riverfront Stadium-based Bearcats would remain with the big fellows . . .

While Orange Bowl officials consider how to insure the safety of LSU-Nebraska fans should racial unrest continue in Miami, tonight's Gator Bowl game has packed Jacksonville. Piedmont Airlines says it chartered the most flights in its 34-year history to transport West Virginia fans to the WVU-Florida State action . . .

At Arizona State, where Devine directs the booster organization, trouble over ASU's lease of Sun Devil Stadium to the USFL Arizona Wranglers: NCAA cites conflict with regulations requiring "clear line of demarcation between college athletics and professional sports." ASU slates "further study" . . .

The beat quickens for No. 1 vs. No. 2, Georgia-Penn State in Saturday's Sugar Bowl, with rival Coaches Dooley and Joe Paterno planning . . . a dinner together, with wives, one night this week. Once, they vacationed as a foursome in the Virgin Islands . . . Heisman Herschel Walker says the game will have no effect on his decision, he still has no intent to turn pro in '83. As to his ambitions of being an FBI agent, someone said Walker's face is so famous it might be tough to do undercover work. Walker replied, "I could just grow a beard."
