Demetris Robertson, the five-star wide receiver who was a late signee for Cal, showed off some of his freakish athleticism in Berkeley this week, as evidenced by this 63-inch box jump.

The 5-11, 180-pounder from Georgia is being counted on to help the Bears make up for the loss of their six top receivers from last year.

Robertson, who won Georgia state Class A track titles in the 100-meter, 200-meter and long jump, picked Cal over Georgia and Notre Dame, among others, in May.
