16. Allen Iverson
Career years: 1996-2011
The most polarizing American athlete at the turn of the century, it's been a while since Allen Iverson broke NBA ankles. In his prime, his swagger and speed had players (and David Stern) shook, but at age 38, his NBA career is on ice. His stans still think that he's All-Star quality though, and they have no shame in putting that opinion into practice. No pun intended.
Iverson was voted into the All-Star game at age 34 while averaging 13.9 points per game, but he left the NBA a bit unceremoniously—he took time off from his last season with the 76ers to be with his ailing daughter, and never returned to the team. Perhaps stans just want one last hoorah out of The Answer. Everyone else just wants him to prove he's washed up.
