Todd Marinovich
Nobody thought Marinovich would emerge as one of the NFL’s biggest party animals. However, the test tube quarterback resented his father after a rigid upbringing. His dad wanted him to become the perfect QB and brought him up accordingly. But Marinovich began partying hard in high school and college before he made it to the pro game.

Remember, the Raiders selected Marinovich ahead of Brett Favre in 1991. They installed him as the starter after they lost the first couple of games that season but Marinovich’s indiscipline cost him. He took cocaine, amphetamines, and other drugs. Finally, he went to rehab and became an artist (via Pro Football History).
