The current Celtics starting lineup is Derrick White, Payton Pritchard, Jordan Walsh, Jaylen Brown, and Neemias Queta. This will be a brand-new lineup, with White and Brown being the only holdovers from last season who are in the starting lineup. 

With Jayson Tatum out for the regular season and Kristaps Porzingis and Jrue Holiday on new teams, the focus is now on Jaylen Brown and Derrick White. They will be counted on by many to lead the Celtics back to the playoffs, albeit with a very shorthanded lineup. 

William Chisholm owns the Boston Celtics. He is the managing partner at Symphony Technology Group. He recently agreed to purchase the Celtics for an estimated valuation of $6.1 billion, officially the most significant current sports team acquisition in all the major sports.
