An interesting note about the Draft: second overall pick Nick Bosa has a colorful family history. Not only is he a third-generation NFLer, but his great-grandfather turns out to be Tony "Joey Batters" Accardo, a major figure in the Chicago Mob.
Accardo rose up the ranks after Al Capone was sent to Alcatraz for tax evasion. Eventually, he became the head of the "Outfit" founded by Al Capone and retained power in the mob for forty years. He preferred to keep a low profile, eschewing a fancy lifestyle to concentrate on accumulating wealth and power. As late as the 1970s, Accardo demonstrated he was not a man to cross -- when his Chicago home was burglarized in 1976, he found out who was responsible and had their throats cut. He lived to the age of 86 and died of natural causes.
The first generation of football players in Bosa's family, linebacker Eric Kumerow, faced scrutiny in his four-year career about his grandfather's ties to the mob. He himself turned out to have no personal connection to Accardo.
