It's always a good idea to keep Hitler's name out of your mouth. In this case, "Last Chance U" Coach Jason Brown sent a text to a German player telling him that he was the player's "new Hitler." He resigned today. LINK.
Brown was former U-M RB Kingston Davis' coach at Independence Community College; Davis was heavily featured on the Netflix series. Davis then transferred to UAB and got kicked off the team and charged with domestic violence in December. LINK.
