Wiedmer: Philanthropy may overtake football as Peyton's greatest legacy

His name was Tyler Frenzel. When he was 7 years old he was diagnosed with leukemia. He spent the next two years of his fragile life moving in and out of Indiana hospitals, fighting a brave fight he could not win.

One of those hospital visits led him to Peyton Manning Children's Hospital at St. Vincent in Indianpolis. He soon became friends with Manning, the Indianapolis Colts' quarterback in those days.

"For two or three months after that, Peyton would invite him to charity events," recalled University of Tennessee associate athletic director for communications Ryan Robinson, who was Manning's personal assistant at that time. "Or he'd have Tyler sit in a suite at Colts games."

Along with former major league baseball player Scott Rolen, Manning soon became fascinated with young Frenzel's goal to build a giant treehouse where children with leukemia could go to, in Tyler's words, "feel normal."
