In a 2010 pre draft meeting, Jeff Ireland of the Dolphins asked Dez Bryant if his mom was a prostitute. Another team asked him if his mother still did drugs. In an interview with Eli Apple in 2017, a Falcons coached asked him if he "liked men". At the 2010 combine, retired DE Austen Lane was asked some doozies; "If you had to murder someone, would you use a gun or knife?","I see you have dreads; you smoke weed don't you?", "If you could kill someone and not get caught, would you?" Toby Gerhart got asked questions about what it felt like being a white RB.
I'm not really sure what goes on in these meetings, or what the purpose is in some of the questions, but there is a long list of teams asking strange and insulting questions of players. Who knows what kind of questions Ronald Jones was dismissive of, but it's not like teams have a history of asking only normal, intelligent questions.
