Just as the Oklahoma football defense appears to have regained its relevance, the Sooners could be losing their defensive architect.
Alex Grinch. who joined the Oklahoma staff in 2019 as defensive coordinator and has improved the Sooner defense from one of the worst among the 129 FBS teams into a top-20 defense in just two seasons, is reported to be interviewing for the head-coaching job at Arizona.
