I started a thread on the ACC forum where this belongs. That said, in response to the preceding post, Bobby Stoops grew up in Ohio. Three of the Stoops brothers played defensive back at Iowa, Bobby, Mike, and Mark. Bobby said years ago he did not want to coach his own son. His son wanted to play at Oklahoma where he grew up. His son may still be on the roster as a non-scholarship athlete.
In his playing days at Iowa Bobby Stoops saw how Coach Bob Cummings was treated by the fanbase when his teams went south, [I was there - real estate for sale signs appearing in their front yard] and how that played out and reflected on and hurt Bobby Cummings, Jr. who played QB. Coach Bob Cummings had been an offensive lineman on one of the 1950s Iowa teams that won the Rose Bowl.
Years ago, Bobby Stoops vowed he would not coach his own son because of his experience at Iowa with Bob Cummings, Jr. I believe his son's desire to play at Oklahoma probably motivated Bobby's early retirement as Oklahoma coach, and perhaps his son had not read the earlier sports articles on this topic. His dad was a real dad, said nothing because he wanted the best for his son, and retired.
I am speculating, but the speculation is an educated guess.
