49ers coach Jim Harbaugh might be losing his edge.
During a recent visit to Six Flags Discovery Kingdom in California, Harbaugh did push-ups with a 1,750-pound walrus named Siku and failed to correct the creature's terrible form. What ever happened to the Harbaugh that blew up at a referee with 5 seconds left in a game and his team up by 10?
I want to see this Jim Harbaugh do push-ups with a walrus. [Deadspin]
