CHICAGO — An assistant for Jimmy Sexton, the most powerful agent in football, stood face-to-face with a client, Laremy Tunsil, the 6-foot-5, 310-pound offensive lineman from the University of Mississippi, in a crowded media room in the Auditorium Theatre of Roosevelt University on Thursday night.
Tunsil had just been selected by the Miami Dolphins with the 13th pick in the first round of the N.F.L. draft. But he was also suddenly at the center of one of the biggest calamities in draft history. Sexton’s assistant, Amy Milam, prepped him for the onslaught he was about to experience.
