The Boston Celtics have re-signed key players from their championship-winning team, including guard Derrick White on a four-year, $125.9 million deal and center Luke Kornet on a one-year contract. Kornet's return, along with re-signing Neemias Queta, bolsters the frontcourt, especially with Kristaps Porzingis expected to miss the season's start due to surgery. The Celtics have managed to retain nearly their entire core, ensuring depth and continuity for another championship run. Additionally, the team exercised its option on reserve wing Sam Hauser, keeping their top nine players from the previous season under contract.
