Reggie Theus has his second assistant coach, according to Brian Windhorst of the Akron Beacon Journal:

Here's the official press release, which notes Natt played with Reggie for the 84-85 Kansas City Kings.I expect Natt will coach the Kings summer league team, while it's been stated Theus will run the practices. Jason Hamm — who was a video coordinator under Mike Fratello two years ago and an assistant under Eric Musselman last year — is also down with the team.
