John Geddert -- the coach of the legendary 2012 Team USA gymnastics team -- has been charged with multiple counts of human trafficking and sexual assault and faces up to life in prison.
... and there's a connection to disgraced Team USA doctor and convicted sexual predator Larry Nassar.
63-year-old Geddert was the head man in charge when the Fierce Five squad won gold at the 2012 Games in London. The team, was comprised of superstars Aly Raisman, Gabby Douglas, McKayla Maroney, Kyla Ross, and Jordyn Wieber.
But law enforcement officials say Geddert shouldn't be celebrated as some great coach -- claiming he's a scumbag who sexually assaulted an unidentified person in 2012 who was between the age of 13 and 16.
