HIGHLANDS RANCH – Consider the weight on Luke McCaffrey’s shoulders:
— His father, Ed, was a star wide receiver and two-time Super Bowl champion with the Broncos. Before Luke’s senior season at Valor High School, his dad became his head coach.
— All three of his older brothers — Max, Christian and Dylan — starred at Valor, won state championships and went on to play FBS college football. Christian, a Heisman Trophy runner-up in 2015 while at Stanford, and a first-round draft choice by Carolina in 2017, just set the Panthers’ franchise record for yards from scrimmage in a single season.
