Three notable quarterback platoons in OU history:
1. Dave Robertson & Kerry Jackson, 1972: The NCAA ruled freshmen eligible for the '72 season, and Chuck Fairbanks and Barry Switzer took full advantage. They made Jackson the backup quarterback and began inserting him into games to relieve Robertson. Jackson, a dynamic runner, was OU's third-leading rusher through four games, with 286 yards on 44 carries, just 30 yards fewer than All-American Greg Pruitt. Then an injury sidelined Jackson, and Robertson played most of the remaining meaningful minutes.
2. Eric Moore & a cast of thousands, 1996-98: In Moore's final three seasons, he started the majority of OU games. But the quarterbacking never was settled. He gave way to Garrick McGee in the 1995 season finale, then spent the next three years giving way to Justin Fuente or Brandon Daniels or Jake Sills or Patrick Fletcher.
3. Jamelle Holieway & Charles Thompson, 1988: Holieway's rebuilt knee rendered the once-magical optioneer a shadow of his former self. But Barry Switzer still started Holieway early in the '88 season, while playing Thompson extensively, too. A 23-7 loss at Southern Cal showed the system wasn't really working, and when Holieway suffered an ankle injury against Texas, the political door was open for Thompson to take over full-time.
