The book also tells of running back Buster Rhymes shooting a machine gun off an OU dormitory balcony to end a snowball fight.
Bosworth said in the book that while he was on scholarship, he lived in a $500-a-month condominium with a big-screen TV and two cars parked outside.
Bosworth, writing that the football program bordered on anarchy, said that coach Barry Switzer did not discipline players who broke the law or circumvented NCAA rules as long as the team won.
"Some guys, especially some of the city guys, would freebase a lot of cocaine," Bosworth wrote. "One day, I happened to see them doing it on the day of the game.
"If you were a star on the University of Oklahoma football team, you could do just about anything you wanted. You had no rules."
The 23-year-old Bosworth left Oklahoma after his graduation in May 1987, disdaining a fourth year of eligibility, and was picked by the Seattle Seahawks in the NFL supplemental draft. He signed a 10-year contract, worth a reported $11 million.
Bosworth, asked by the Associated Press to elaborate on his charges after practicing yesterday with the Seahawks, declined to talk about the book. Calls to Switzer's office went unanswered and phone calls to his home received a busy signal or a recorded message.
Gary Wichard, Bosworth's business manager, characterized the book as giving a true picture of big-time college football.
"Before saying anything publicly, I want to have an opportunity to look at the entire book," Oklahoma athletic director Donnie Duncan told the Morning News.
A snowball fight in 1984 outside the athletic dormitory ended abruptly when Rhymes fired "about 150 rounds out of an Uzi machine gun," wrote Bosworth.
"Somebody hit him with a snowball. He got a little upset," Bosworth wrote of Rhymes. "So right in the middle of the fight, Buster went up to his room, opened his door, and let fly with this Uzi above all their heads. Just a few innocent warning blasts."
Bosworth was suspended from the 1987 Orange Bowl because a drug test detected the presence of a steroid in his system. Bosworth said he took the steroid under a doctor's care and before the NCAA had ruled the drug illegal. But his teammates weren't as careful, he wrote.
"Steroids were about as common as Anacin in our locker room. I'd guess about half the guys on the team took them just to look good . . . and another 20 to 25 percent took them seriously to get strong and put on weight," Bosworth wrote.
