Why shouldn't retired players coach right away? Well because you might become coach of someone you played against in heated 7-game playoff series two years in a row. In other words, someone you hate, who also hates you. As was the case for Phoenix Suns coach Danny Ainge, and ex-Houston Rocket Robert Horry.

Although.. . there is an argument to be made that the opposite is true-- retired players should rush into coaching and hope to have an enemy on their team. And perhaps all players should hope to be coached by their enemy. Because this beef, while surely unpleasant for both parties in the moment, was good for Danny Ainge's image, and was a career boon to Horry. I'll explain. In the video. Not here, there's no time, bye!
