All-Southern Section pick Nigel Clay of Fontana, one of the top offensive line prospects in the country, Thursday night picked Oklahoma over USC and gave a verbal commitment to play for the Sooners.
Lineman Mark Vander Poel of Chino, who has been playing organized football for only two years, was also considering the Trojans, but decided to attend Colorado. Defensive back Paul Behrman from Norman, Okla., gave them another near miss earlier in the week when he picked Texas.
