Focus Daily News Share via: ‘His Own Coaching Tree’ (CEDAR HILL, TEXAS) Carlos Lynn was the defensive coordinator on the first-ever Cedar Hill High School State Football Championship Team in 2006. A relatively new school located 13.5 miles northwest, across Joe Pool Lake, noticed Lynn’s talents and hired him as the head coach of Arlington Seguin High School, where he coached for a decade. Lynn had worked on the staffs of Robert Woods (who was his high school coach at Wilmer-Hutchins) and Joey McGuire. Now, Lynn – who just completed his fourth season at Cedar Hill with a trip to the UIL Class 6A Division II State Championship Game – has his own coaching tree. And it has tripled in size this week.
