12. Johnny Bach
Some people make excellent coaches, but just don’t have the capacity to be a great head coach. Bach is a prime example. He’s a brilliant mind but just couldn’t cut it on the biggest stage of them all. After a brief spell as interim coach of the Golden State Warriors, they gave him the full-time job.

In short, they failed to post a winning season during his time in the Bay. A 22-60 record in his second season summed up how truly awful they were. Then his last year in charge saw them finish at the bottom of the Western Conference. Finally, he jumped ship for a supporting role with the Bulls.
