WHITE SULPHUR SPRINGS, W. Va. — The Greenbrier Resort sits on 11,000 acres and features four golf courses, 20 dining options and one coach with an office. Sean Payton helped design the football footprint that led the New Orleans Saints to escape the heat, if not the internet, for three straight training camps here beginning in 2014. As Payton rode around in his golf cart surveying the grounds this week, often flanked by family and friends, it is clear why he loves West Virginia. But with apologies to John Denver, Payton’s “almost heaven” almost never happened.
