Like a few of his teammates,
Harry Miller started his own company, an online shop through Lynbrook Swag that sells clothing apparel with his personal logo of an "H" on a shield. Unlike many in college sports who started selling their likeness earlier this month, Miller's company sends 100 percent of the profits to his non-profit endeavor, M4N, "to provide education, food, medicine, physical therapy and discipleship for the kids at our school in Los Brasiles, Nicaragua."
Here's a link to his store:
