According to numerous reports:

He’ll be an assistant to Juwan Howard, who served on Erik Spoelstra’s Miami staff from 2013 to 2019 and is now taking his first head coaching job.

Personally, I love the move for Martelli. He coached St. Joe’s since 1995 and is now 64 years old, and while I’m sure he could have landed a head coaching gig at a much smaller school, this is an opportunity to go to a huge program with unlimited resources and help a young coach make a significant transition.

It shows me that Howard understands that this is gonna be quite the jump, so bringing in an uber-experienced guy like Martelli while retaining John Beilein assistant Saddi Washington makes a lot of sense to me.

Good for Phil Martelli. New experience and a unique challenge.
