I was excited when he fell to us in the 4th, but I never really watched a lot of highlights on Miller until AFTER he was drafted.
Watching the film, two things stood out quickly
1) Vision - this kid sees the hole quickly, and anticipates tacklers coming in at angles very well.
2) Smoothness. This is difficult to quantify. Yes, he's fast. What caught my eye is that he's EFFORTLESSLY fast. When he's accelerating, his head barely moves. One video I watched suggested he's reminiscent of Clinton Portis. I disagree.
The guy who he reminds me of (and before I get ripped, I'm not COMPARING him to this guy) came tumbling out of some remote corner of my memory.
I said "Holy ####, he runs like Eric Dickerson."
