Alexander's contract extension sets up a complicated calculus the Thunder, the youngest roster in the NBA, must navigate.

A week after an NBA championship, the Oklahoma City Thunder have smashed open a championship window that won't close for a while. They have reportedly signed Shai Gilgeous-Alexander to a four-year, $285 million contract extension, per ESPN's Shams Charania.

The Pacers’ top scorer is Pascal Siakam, and he dented the Thunder for seven first-quarter points. Siakam scored nine points the rest of the game and made just two of seven shots. Jalen Williams had most of the defensive duties on Siakam. When Haliburton went down, Indiana needed Siakam’s scoring more than ever, but it never came.
