CHARLOTTE, N.C. -- David Shaw remembers that look.
Of all the amazing things Christian McCaffrey achieved on the field at Stanford, his college head coach remembers the look on McCaffrey's face on his way to an early-season Monday night practice in 2015, after learning he was being held out in order to rest.
It was that look that personified McCaffrey's intense competitive nature. It was that look that made Shaw fully grasp what the Carolina Panthers and NFL now are seeing on a weekly basis -- why McCaffrey is special beyond his athletic ability.
