Pflug signed a national letter of intent to play for Coach Kent Kessinger's Ottawa Braves last week.
As one of only two starters on the 2011 squad that played both offense and defense, Pflug was key to the Wildcats' success this fall.
"Justin was a great football player for us this season," said Cassville head football coach David Large. "Offensively, he combined with Josh Lannum to be the guys we ran behind most of the time. Defensively, he was one of the best defensive ends we've ever had. Teams ran away from him most of the season."
Pflug earned a host of postseason awards for his performance on the field. He garnered first team All-State honors as defensive end from both the Coaches Association and Associated Press. In addition, Pflug was named Big 8 Conference Defensive Player of the Year and also received first team Big 8 honors as a member of the offensive line and defensive line.
In his role as defensive end, Pflug was also selected to the All-Region, All-Ozarks and All-District first teams.
"Justin is a great young man that should have a lot of success at the next level," Large said.
Ottawa University, an NAIA school, is a member of the Kansas Collegiate Athletic Association that includes Bethel College, Bethany College, Friends University, Kansas Wesleyan University, McPherson College, Southwestern College, Sterling College, Tabor College and University of St. Mary.
During the 2011 season, the Braves went 9-3 and made the NAIA playoffs. Kessinger is 50-35-0 in his eight years at the helm of the Ottawa program.
