One fall day in 2006, national treasure Marshawn Lynch was seen whipping an injury cart in a herky-jerky fashion across the Cal Bears field following a particularly sweet victory. This expression of pure joy would not have been possible without Mac Dre.

Hailing from the land of "Valley Joe," Mac Dre professional rapped for nearly twenty years but didn't gain widespread recognition until the very end of his career and after his death. He was gunned down in Kansas City in 2004, an unsolved murder case that remains the great tragedy of Bay Area rap. The silver lining is that hyphy movement was about to explode, and he would be its patron saint.
