Marshawn would respect all these father figures, Delisa says, but he grew closer to his mom, too. It was Delisa who had fed him candy ever since his Pop Warner days, giving him Skittles (yes, that's where his other nickname comes from) and calling them "power pellets" to get him amped for games. And it's Delisa who was the inspiration behind the "Mama's Boy" tattoo scrawled across Marshawn's back.
