Overtime Elite’s coaching staff is run by Kevin Ollie, who coached UConn to a national championship in 2014. The players are given personalized nutrition plans and training programs. They are marketed across Overtime’s social media network. (So far, sponsors include Gatorade and State Farm, which signed multiyear, eight-figure contracts with the league. Topps has a licensing deal.) And in the most obviously radical departure, each player gets a small share of the company and earns a salary of at least $100,000 annually, plus bonuses, depending on the contract he has negotiated. Jalen Lewis and some others make more than $500,000. (“There is a marketplace,” says Aaron Ryan, a former N.B.A. executive who has been hired as the league’s commissioner, “and players have varied value.”) In return, they have agreed to forgo their remaining years of high school and any chance of playing in college. That means no state titles or prom dates, no strolls on leafy campuses, no March Madness or Final Four. They also allow Overtime to use their names, images and likenesses, the same assets that college athletes have just earned the right to monetize for themselves, though the Overtime Elite players are permitted to strike their own deals with sponsors in noncompetitive categories.
