When updating my rankings after the NFL draft, the biggest risers were obvious. Highly-drafted rookies who landed in situations where they’re expected to see lots of opportunity, such as Rashaad Penny, immediately became more valuable. But so too did players who dodged the bullet of extra competition being added. While Marlon Mack and Kenyan Drake have both been the focus of post-draft hype, Lamar Miller seems to be flying under the radar.
