PLANO, TEXAS The Medical Examiner in Collin County says heart issues associated with heat exposure killed a football coach on the football field at Prestonwood Christian Academy Monday morning. The football equipment stood unused on the field at Prestonwood Christian Academy today. Just a day after the school's beloved assistant football coach, 55-year-old Wade McLain, passed out during the varsity team's first practice of the year. "It's just not right that something like that happened to such good people. There's so many rotten people walking around in this world and it's sad to lose the good ones," said Neighbor Judy McBroom. Neighbor, Judy McBroom, says Coach McLain was a strong family man who always offered to help her with yard work. http://www.the33tv.com/news/kdaf-prestonwood-football-coach-heat-death-story,0,6812816.story R.I.P.
