Marshall Henderson
There was a time when Henderson was one of the biggest stars in college basketball. The Ole Miss athlete attracted the nation’s attention with his controversial views and actions. We’re not here to talk about his racism because that’s for another day. But he had plenty of moments of bad sportsmanship too.

Henderson brought March Madness to another level after Mississippi crashed out in the third round. He infamously lifted his middle finger to LaSalle’s fans during the 2013 NCAA Tournament. This wasn’t the most family-friendly gesture and the NCAA reprimanded him for his action (via USA Today Sports).
