While NFL teams find this information critical to understanding a prospect’s fitness and capabilities, others suggest the whole exercise could unwittingly violate federal law. The University of Pennsylvania Law Review published a study last month that recommended the NFL reconsider the way it conducts its annual job fair. Researchers at the University of Houston Law Center and Harvard Law School say asking players to submit to invasive medical exams appears to violate both the Americans With Disabilities Act — which despite its name provides protections to all prospective employees, disabled or not — and the Genetic Information Nondiscrimination Act, which prohibits employers from asking about family history or using that information when making hiring decisions.
