Pelini was the last former assistant to face Stoops. In the 2010 Big 12 championship game, Oklahoma rallied to beat Nebraska inside Cowboys Stadium in Arlington, Texas — the same venue where Stoops and Sumlin will meet.
Sumlin coached under Stoops from 2003-07, leaving to become Houston's head coach. This is Sumlin's first season leading Texas A&M.
“Come Jan. 4, we're gonna go out there and go at it,” said OU assistant Bobby Jack Wright, who's been with Stoops since he arrived in Norman.
“It's not gonna change anything. We're gonna be friends at the end of the day, but for about four hours, we're gonna try to beat them, and for four hours they're gonna try to beat us.”
