Stanford RB Christian McCaffrey is a tireless workout warrior built to handle heavy workloads, according to his collegiate teammate Graham Shuler. ‘We do this thing here called the Gator Run,’ Shuler said. ‘It’s one of our most intense off-season training things. It’s when you load up one of those utility vehicles, like a Gator, with 600 pounds in the back and three coaches are riding in it. We push it all around campus, and it’s a sprint. It’s really rare for anyone to push it over 20 times. When we did it this summer, Christian pushed it 43 times. He took 43 turns.’
