20. Kobe Bryant
Career years: 1996-present
There are plenty of Laker Nation reps and Kobe stans to drown out the hate, but that doesn't mean it doesn't exist. As loathed as he is loved, Kobe Bryant remains one of the most polarizing players in the NBA going into his 18th season. He's getting up there in years and his body seems to quit on him every season as his career winds down, leaving blood in the water for Kobe haters to flourish off of.
