WASHINGTON — NCAA President Mark Emmert told a Senate committee Wednesday he supports "scholarships for life" and other reforms in how athletes are treated, then did such a good job of casting himself as a powerless figurehead that one senator told him: "I can't tell whether you're in charge or whether you're a minion." Emmert faced a skeptical Senate Commerce Committee and said he feels college sports "works extremely well for the vast majority" and that the overall current model of amateurism should be preserved. But he listed several changes he'd like to see enacted.
