NORMAN — In 1976, Billy Brooks, Lee Roy Selmon and Joe Washington all went high in the first round of the NFL Draft. Not since has Oklahoma had to replace that kind of star power in one year. Until now. Sam Bradford, Gerald McCoy, Trent Williams and Jermaine Gresham all are expected to go in the first round of next month’s draft, which would be the highest number in program history. Even though Bradford played sparingly and Gresham not at all last season due to injuries, the program has been defined by those four players in recent ears. Next season, slot receiver Ryan Broyles, running back DeMarco Murray, defensive end Jeremy Beal and linebacker Travis Lewis will supply the star power as OU regroups from a disappointing 2009 season. But after that? Spring ball is a time to cultivate a program’s future batch of stars. Here are four up-and-coming names that will be on full display during the next two months: →Linebacker Ronnell Lewis: Nicknamed "The Hammer,” Lewis proved worthy of that moniker during the Sun Bowl when he delivered a couple of slobber-knocking hits. Defensive coordinator Brent Venables will attempt to find Lewis a home during the spring. But whether that’s on the outside or the inside, Lewis should add to the grand linebacker tradition at OU before his time is done. →Cornerback Demontre Hurst: From the day he stepped on campus, Hurst has stood out, drawing loads of praise last preseason. This year, however, the pressure will be on Hurst, who will fill the starting role vacated by Dom Franks at field corner. Hurst hits harder than his 5-foot-9, 165-pound frame would suggest, and he has enough athleticism to become a big-time playmaker in the Big 12. →Defensive tackle Jamarkus McFarland: Defensive tackles under line coach Jackie Shipp usually spend their true-freshman seasons redshirting and adjusting to the college game. Just ask Gerald McCoy. But last season, the Sooners couldn’t resist putting McFarland on the field, and he responded by helping plug Stanford’s power rushing game during the second half of the Sun Bowl. McFarland possesses a similar pedigree to McCoy and Tommie Harris, and he has the potential to become OU’s next first-round defensive tackle. First, McFarland must shoulder the load on the interior while Adrian Taylor heals from a broken ankle and the team generates some much-needed depth at the position. →Safety Tony Jefferson: Everyone from Florida to USC wanted the multi-talented Jefferson, whom the Sooners plucked out of Chula Vista, Calif. Jefferson, who enrolled early at OU, was a two-way star in high school and will be used as a safety in Norman. Like ex-Sooner safety and fellow California native Roy Williams, Jefferson is an explosive hitter and has enough ability to win playing time at strong safety immediately.
