According to sources, the Oklahoma CityThunder are going to hire the NBA's best shooting teacher as an assistant coach.

During his 17 seasons with the San Antonio Spurs, he was credited with the development of young players like Kawhi Leonard, Tony Parker and Dejounte Murray, as well as veteran players like Richard Jefferson.

Sources said that the sides couldn't agree on a new contract and that the 61-year-old left the team. He is one of the highest paid assistants.

Their paths crossed in San Antonio in the mid-2000s. The team has young talent and more expected on the way.

Oklahoma City is in the second year of a rebuild and has already gathered young talent. Mark Daignault's coaching staff will help develop the shooting habits of the young players.
