NORMAN — Oklahoma juniors Curtis Lofton and Duke Robinson were among 28 players named consensus All-Americans by the NCAA on Monday. Lofton, from Kingfisher, led the Sooners with 141 tackles from his middle linebacker position, while Robinson, a right guard from Atlanta, anchored the OU offensive line, which allowed 11 sacks through 13 games. OU coach Bob Stoops has called Lofton the most productive linebacker he has coached in nine seasons at OU. Robinson, at 6-foot-5, 350 pounds, has been drawing national attention since before the season began. Consensus All-Americans are determined by a point system, incorporating five All-America teams: American Football Coaches Association (First Team), Associated Press (First, Second and Third Teams), Football Writers Association of America (First Team), The Sporting News (First and Second Teams) and Walter Camp Foundation (First and Second Teams). The system awards three points for first team, two points for second team and one point for third team.
