If there is a textbook that explains precisely how to conduct oneself upon becoming the head coach of a new team then Brad Stevens has followed every step to a tee.

But if such a book doesn't exist then Stevens is creating the blueprint for others to follow.

Since becoming the 17th head coach in the history of the Boston Celtics Stevens formerly the coach at Butler University has said and done virtually all the right things.

He aced his introductory press conference by being remarkably humble as he spoke about the tradition of the storied franchise. He later flew to Louisville to meet with his star point guard Rajon Rondo.

And in another smart gesture Stevens has sent letters to former Celtics players inviting them to return to games and practices and to stay in touch with the franchise.

Minus the address and some contact information here is the text of one such letter the Globe has viewed that Stevens had sent to former Celtics guard Kenny Anderson.

The letter itself is dated July 22 2013 a few weeks after Stevens was hired as the Celtics' head coach.

"I am truly humbled and honored to assume the responsibilities of head coach of the Boston Celtics. The Celtics’ mystique history culture and tradition speaks for itself. There is nothing else like it in all of professional sports.

"At the press conference announcing my hiring I was in awe looking up at the 17 championship banners. I am first and foremost a fan and admirer of the Boston Celtics and what has been accomplished by each of you.

"On behalf of the Boston Celtics management staff and players I write you to come around any time. Please know that you are cordially welcome to attend our practice sessions home games at the TD Garden games when we are on the road and Celtics events in our community.

"I look forward to meeting you in the near future. Continued success and well wishes."
