Kyle Shanahan calls Christian McCaffrey and Fred Warner “borderline psychos” because getting the most out of their talent takes an obsession not everyone has “When you watch how Fred [Warner] acts, you watch how Christian [McCaffrey] acts, they’re different.” “They’re borderline psychos. They’re obsessive-compulsive with certain things.” “And in order to get the most out of your ability, you do have to be that way, and not everyone is that way. It’s rare to have both. It’s rare to have the talent and that type of mindset.” “And not everyone comes in with that mindset, but you can learn how to have it.”
