What happened: George said Tuesday that sharing the floor with Tatum is a natural fit because he has already succeeded next to another star wing. Boston introduced him alongside Mike Conley as the club opened the next phase of its roster overhaul after the Brown trade. George added that he understands the emotion Celtics fans still carry from Brown's exit.

Why it matters: Boston is trying to reset around Tatum after a first-round playoff exit, so George's ability to defend, create as a secondary ballhandler and work in shared usage is central to the plan. The partnership has been building for weeks, with George and Tatum already working together in offseason sessions before camp.

What to watch: Training camp should give the first real look at how Boston splits on-ball work between George and Tatum. George's health will stay in focus after two injury-disrupted seasons.
