The Detroit Pistons have come to terms on an agreement with Monty Williams to become their next head coach, league sources told Yahoo Sports.

The pact is sizable, with the Pistons coming to the table with a guaranteed $78.5 million, six-year contract, plus two additional team option years that could take it to $100 million, sources said. Pistons owner Tom Gores, as he was in the case of Dwane Casey in 2018, was heavily involved in the courtship of Williams after he hit the coaching market weeks ago.

The Pistons were in discussions with Milwaukee Bucks assistant coach Charles Lee and Overtime Elite’s Kevin Ollie, and Lee had taken the pole position of the two. The Pistons initially made overtures to Williams, but Williams seemed unsure about coaching this season and looked to take the year off.

The relationship between Pistons general manager Troy Weaver and Williams goes back to Williams’ time in Oklahoma City, and Gores kept in contact with Williams over the past few days, as Williams began to reconsider coaching next season.
