What happened: Recent workouts included Mike Conley, Jayson Tatum, Paul George and Derrick White, with more teammates expected to join. Pritchard believes Mitchell Robinson, Neemias Queta and Luka Garza can turn Boston's frontcourt into a strength.

Why it matters: The Jaylen Brown trade projects to give Pritchard more offensive responsibility within a reshaped rotation. Pritchard has also weighed a Celtics extension, adding a contract question to his expanded role.

What to watch: Watch how Boston divides its offense and leadership duties when the full roster convenes.
