There were a couple of things not specifically mentioned as to timeline. At the time, the Oklahoma Journal and Al Eschback were essentially what James Hale is today, close to OU recruiting. Via the column and some radio interviews, I got the impression that:
1. USC, Texas, and OU were in the hunt for Kerry Jackson. Don't underplay his talent. He had never been a wishbone specialist, but he was fast, could run, and could throw the ball seventy yards on a line, although perhaps not to where he was aiming. But, USC and OU backed ot of recruiting him, leaving UT as the only school recruiting him during the last week or two.
2. Royal wanted Jackson to be the first black superstar at UT which was somewhat late in recruiting blacks. He could be the first black QB.
3. The principal at Galveston Ball, supposedly a Texas alum, changed a grade from a D to a C, making Jackson eligible. At the time, there were no ACT or SAT requirements.
4. Through Michael, OU learned that the grade had been changed.
5. On signing day, Royal was outraged that OU slipped in and signed someone that he thought he had locked up. Every team in the SWC learned that you don't beat Royal without retaliation.
Now, as I understand, it was perfectly legal for a highschool principal to change a grade. I'm not sure that any rule was violated. But, Royal was on the warpath, and I suspect that he helped dredge up everything he could to nail OU with the NCAA. I don't think OU had any violations with respect to Jackson.
Fortunately, while Jackson had the notoriety, it had been apparent to me that Davis was the best of a lot of freshman QBs on the freshman team at actually running the team, and he was about seventh in a group of six. By the time Jackson was eligible, he hadn't learned how to control his running or his arm, and Davis was on the way to another undefeated season.
My pick was what could have been. We got the top running back out of Texas, and he was as good as advertised, Mike Thomas of Greenville. Unfortunately, he had Pruitt and Washington in front of him, and we went to UNLV where he starred and the Washington Redskins where he starred. I think he did get to play and launched a 90 yard TD run on his first play from scrimmage for OU, or am I thinking of the kid from Conroe a year later.
