For the last two seasons I have been under the belief that Eddie Lacy isn't a power back, he's merely a big back. Meaning that he has the build and the frame to be a power back who trucks defenders and wears them down as the game goes on. While his frame is different, he could be like a Marshawn Lynch style runner... but he's not.
Lacy seemingly prefers to run around defenders with little shifty cuts and spin moves rather than run through them - and that's fine. It just makes watching him a little frustrating for me because I would rather not see all that size slow him down and turn what could be home runs into 10 to 15-yard runs.
