Richardson was an NFL legend before he single-handled destroyed his reputation. The former Panthers owner sexually harrassed many of his female employees and this made his position with the franchise untenable. First, it’s not true to say that it was a mistake because he intended to commit these disgusting acts.
But it was a terrible error of judgment to bring this vile behavior to the workplace. Nobody knows what he was thinking because he was in a position of power. It was likely that somebody would file charges against him eventually. In the end, he paid the price for his disgraceful antics and abuse of authority (via Forbes).
