Take a look at the photo below. The big guy is Derrick Henry. He went to the same school, Alabama, as the “small” guy on the left, Mark Ingram.
Ingram is a “normal sized” running back (215 pounds), and maybe even on the big side. Henry is a monstrous freak of nature, and the prototype for what a modern power back can bring to the table. The picture is striking, as is the memory of Henry carving up New England and Baltimore in the playoffs.
