Christian McCaffrey is a once-in-a-generation type of talent, humble yet confident enough to handle any sort of situation, and both delicate enough and explosive enough to make defenders fall over, untouched. He has a unique way of making players look like they've never played football before and voters look like they've never watched it before.

The last time there was this much uncertainty on the offensive line was heading into the 2014 season, when Stanford had to replace three starters on the offensive front.
