Professional sports are PR driven to a large extent. If you want the public perception to be that you care about employees and the public at large, it's hard to sell a womanizer (?) as the head coach when he's *currently under suspension* for his workplace issues. It's not like Ime has done his penance, or made amends.
But, from a non-PR perspective, the Nets don't have to agree with the Celtics punishment. Maybe they're convinced that the entire thing was more about perception than fairness and due process. Maybe the Celtics were extra tough on Ime because they have a history of a hostile work environment that we don't know it. It's impossible to know if the Nets are making a sensible basketball decision without knowing all of the facts. But again, from a PR standpoint? Terrible.
