Alfred Morris is not the next Terrell Davis, he's the first Alfred Morris. To my eyes he's distinguished by having elite vision and anticipation. He doesn't just see the holes, he sees them before they open up, and slashes right through.
But I want to compare Morris to Terrell Davis anyway, because the similarities are uncanny. Obviously both are hand-picked Shanahan backs drafted in the 6th round. But there's more.
For example, both are really really slow.
