Yes, that is him again. He's back.
Sean is a fantastic official. The NBA would do great to hire him back.
The NBA looks about ready to hire another woman. Lauren Holtkamp (#37) has been working pre-season games. She may join Violet Palmer (still working) and Dee Kantner (who was fired after 5 years) as the 3rd female official.
Zach Zarba gave Corbin's number back to him (#33) and has taken Nunez's number 28. Tommy Nunez Jr. has been fired.
