Marshawn Lynch (Retired / Honorable Mention)
There are two things we know about Marshawn Lynch: 1) he is as ferocious a running back as we’ve seen in recent memory, and 2) he marches to the beat of his own drum. His off-season workouts are a testament to both of those.
After being away from football, when Lynch was preparing to rejoin the Oakland Raiders prior to the 2017 season, he got in shape by performing all his workouts on the beach, but while wearing combat boots to up the difficulty level of training on sand. He did everything from ladder drills, jumping over obstacles, and even catching passes with one hand.
