The NFL Scouting Combine—where college football’s hottest prospects are put through their paces in front of pro talent spotters—is well known for its tests of physical endurance, but Louisiana State running back Derrius Guice has lifted the lid on some of the questionable mental tests he was put through—including being grilled on his sexuality and on whether his mom was a prostitute. “It was pretty crazy,” Guice said in an interview on SiriusXM radio aired late Wednesday. “Some people are really trying to get in your head and test your reaction.... I go in one room, and a team will ask me do I like men, just to see my reaction. I go in another room, they’ll try to bring up one of my family members or something and tell me, ‘Hey, I heard your mom sells herself.’” Two years ago, the NFL opened an investigation after an Atlanta Falcons coach asked Ohio State cornerback Eli Apple if he was gay during the Combine. The Falcons later apologized.
