Williams, an offensive tackle, had been named an All-American earlier this month as part of the American Football Coaches Association team. He is now joined by McCoy, the school's 150th All-America selection. Both were named to the first team.
McCoy also became the 37th Sooner player to earn All-America honors in more than one season. He was named to All-America teams by The Sporting News and Sports Illustrated after the 2008 season.
The junior defensive tackle from Oklahoma City, was the target of frequent double-team blocking schemes during the 2009 season, but still tallied 31 tackles, including 14.5 for losses. He also registered five sacks and a team-high 10 quarterback hurries.
McCoy broke up two passes, forced one fumble and recovered one fumble. During the season he broke the school record for most consecutive starts by a defensive lineman. That total now stands at 38.
Williams, a senior from Longview, Texas, missed the regular season finale 27-0 victory over Oklahoma State with an injury, but still led OU this year with 885 plays and 102 knockdown blocks. He has been a three-year starter for the Sooners.
The Walter Camp All-America team is selected by the head coaches and sports information directors of the 120 Football Bowl Subdivision schools and certified by UHY Advisors, a New Haven, Conn.--based accounting firm.
The 2009 Walter Camp Player of the Year and members of the All-America team will be honored at the organization's national awards banquet on Saturday, Jan., 16, 2010, at the Yale University Commons in New Haven. In addition, the Foundation will honor three individuals - NFL Hall-of-Famer John Elway (Stanford), former NFL All-Pro David Fulcher and ABC broadcast personality Robin Roberts (Southeastern Louisiana) - with major awards.
