One thing I noticed about Perine vs. Mixon (and a lot of other backs) is that Samaje seems to me to run a lot more like a wide receiver than a running back or even tight end. They tend to have a bit of a crouch to their stance when running. Perine is mostly vertical. And defenders go more for his upper body versus trying to take out his legs, letting him get yards after contact. I dunno maybe I’m nuts but that’s what I see on the videos.
