45. Damon Arnette
Most players receive hate because their fanbase has irrational expectations. Usually, the athlete hasn’t done anything that justifies taking a lot of abuse. However, Arnette is a special case because he acts like a psychopath in the public domain (via The Athletic).

Sometimes fans leave anonymous death threats in a cowardly move on social media. But this time Arnette brandished guns and threatened somebody’s life in a shocking video. In the end, the Raiders cut him because he brought the franchise into disrepute.
