Looking like Asiata if you need someone right now and McKinnon if you are looking for higher upside later in the year.  Here is a nice blurb on McKinnon from rotoworld: As you can read in the Zach Whitman column linked below, SPARQ is a metric developed by Nike to apply a single composite score to a player's athleticism. An elite NFL athlete is around 140 and the 150+ range is reserved for the Calvin Johnson types. The point is that although McKinnon is very raw as he comes out of Georgia Southern and has very little pass pro experience, he's a freak. "Backs with McKinnon’s speed, lower-body explosiveness and upper-body strength just don't exist," wrote Whitman. He'll be a change-of-pace back behind Matt Asiata to start, but his fantasy ceiling is far higher. McKinnon is a solid stash while we see where Adrian Peterson's case goes.
