Watch: 4-star Cal commit lands 63-inch box jump

The athleticism of 4-star Cal commit Demetris Robertson is off the charts.

Perhaps in an effort to prove he has the determination and ability haul in passes like larger players, the 5-foot-11, 180-pound wide receiver recently completed a 63-inch box jump.

Robertson is rated 62nd on the ESPN 300 as well as being the sixth rated receiver in the country for the 2016 class.
