During his freshman year in college, he was cited thrice: for breaking car windows with a BB gun, being present when two men threatened a neighbor with a gun at his apartment, and mistreating three puppies.As a sophomore, he was accused of punching a woman outside a bar in Tallahassee. He pled not guilty, was acquitted, and returned to football.The troubles persisted into Cook's pro career, as in 2021 his ex-girlfriend accused him of domestic violence. He denied the allegations.Assessing the next landing spot for Dalvin CookWith Cook gone, the Vikings are expected to lean on Alexander Mattison, who has rushed for 1,670 yards and 11 touchdowns. As for Cook, he has already teased a linkup with the Miami Dolphins via Instagram:Dalvin Cook at Hard Rock Stadium in the Miami area (via Instagram/@dalvincook)According to CBS Sports' Jordan Dajani, the Dolphins would make the most sense for Cook - he was born in the Miami metropolitan area and played high school and college football in Florida. When the Vikings visited the Dolphins last season, Cook told Sports Illustrated:"It's gon' be fun. I'mma have a lot of supporters down in my hometown. It's always good getting back into some warm weather."This is what I dreamed about, this is a kid's dream, just living in it, trying to take advantage of the moment. If you know me, I just like to have fun. So I try to enjoy the moment, man, because you don't get these back. We only play Miami every so many years, so gotta take advantage of these type of games."Other options that Dajari floated around are the Buffalo Bills, where his younger brother James plays; and the Arizona Cardinals, whose primary rusher James Conner needs a backup, given his injury history.
